data sheet K-LD7 digital radar transceiver Features Applications Description Small and low cost digital 24 GHz radar motion detector Measures speed, direction, distance and angle of moving objects Low current consumption Typical detection distance: 15 m for persons / 30 m for cars Target list output over serial interface Integrated FFT signal processing with tracking 4 configurable digital outputs Power supply range from 3.2 to 5.5 V 3 4 patch antenna with 80 / 34 beam aperture Distance triggered movement detection applications Simple gesture recognition Indoor and outdoor lighting control applications Pedestrian counting Traffic counting The K-LD7 is a fully digital low cost Doppler radar that can mea-
sure speed, direction, distance and angle of moving objects in front of the sensor. The digital structure and wide power supply range make it very easy to use this sensor in any stand-alone or MCU based application. The sensor includes a 3 4 patch antenna radar front-end with an asymmetrical beam and a powerful signal processing unit with four configurable digital outputs for signal detection information. A built-in tracking filter makes the sensor output even easier to use. The serial interface features the possibility to read out a target list with speed, direction, distance and angle information of all moving objects in front of the sensor or to digitally configure the sensors detection parameters. There is no need to write own signal processing algorithms or handle small and noisy signals. This module contains everything what is necessary to build a simple but powerful motion detec-
tor with distance and angle information. A very small footprint of 38 25 13.5 mm gives maximum flexibility in the product develop-
ment process. For fast prototyping an evaluation kit (K-LD7-EVAL) is available which features powerful signal visualization on a PC.

cessor with tracking and a fully digital serial interface. The RF frontend features one transmitter with a mo-
dulation input and two I/Q receivers. The signal pro-
cessing unit modulates the frontend with a frequency step (FSK modulation) and samples the analogue I/Q Doppler signals for both transmit frequencies and for both receiving antennas. The processing of this sampled data allows the measurement and tracking of speed, direction, distance and angle of moving objects in the front of the sensor. The processing of the K-LD7 uses different proces-
sing stages to measure and track the speed, direc-
tion, distance and angle of moving targets. The last stage implements a configurable detection filter which generates a detection based on parameters like distance, angle or speed. The detection filter output is routed to the digital outputs. To get the full control in an application it is possible to read out the data of each processing step over the serial interface.

Copyright reserved! RFbeam Microwave Angle measurement 2 3 The angle measurement is based on the angle of arrival principle. After the detection of all raw targets above the threshold, the angle for each target is cal-
culated based on the phase difference between the two receiving channels. 4 The angle is calculated in degree and valid between 90 . If an object has an angle of zero it is directly in front of the sensor. A positive or negative angle defines if the target is more on the right or left side of the sensor. Figure 5: Positive and negative angle definition Every moving object in front of the sensor generates a Doppler frequency at the analogue outputs of the RF frontend. This Doppler frequency is proportional to the speed of the object. Moving direction is defined by the phase shift between the I/Q signals. A The K-LD7 calculates the speed and the direction for all raw targets. The direction is represented by the sign of the speed. A positive speed represents a receding and a negative speed an approaching movement. The calculated speed is only correct if the movement of the object is radial to the sensor. If the movement is tangential the speed needs to be compensated by the angle of the movement compared to the sensor. vreal =

cos() moving object radar sensor Distance measurement The distance measurement is based on the FSK principle. The signal processing unit quickly changes between two discrete RF frequencies and measures the ADC values for both transmitting frequencies which are available in the raw ADC data (RADC). After the detection of all raw targets above the threshold, the distance for each target is calculated based on the phase difference in both ADC signals. 1 B C D

A moving person for example generates several raw target points with different speeds and different distances created by the torso, the legs and the arms. This generates a so called point cloud of different raw targets from one object. Depending on the environ-
ment where the sensor is used it will also see more or less reflexions generated by the moving object. The number of raw targets can be controlled by adjusting the threshold offset which is described in more detail in chapter Threshold offset on page 10. Figure 7: Raw targets vs. tracked target To get a more usable output the sensor features a tracking filter to cluster and track the dominant target based on the raw targets. The filter includes a sup-
pression of reflexions, vibrations and interferences and can also predict temporary lost targets what generates a smooth output. The tracking filter can be adapted to various applications via the parameters Tracking filter type and Vibration sup-
pression which is described in more detail in chapter Tra-
cking on Page 10. The filter can track only one target up to a dis-
tance of 30m. Micro detection The micro detection is a feature to detect very slow speeds in short range applications. It takes advantage of an algorithm that analyses the DC bin of theFFT to detect very slow speeds. The micro detection is independent from the normal detection algorithm and always enabled. It is available in the detection data structure DDAT and can be used to retrigger thehold time. Further it is possible to adjust the sensitvity of the micro detection over the parameter Micro detection sensitvity. The sensitivity of the micro detection depends on the used speed range setting. To get the best results always set the speed range first before adjusting the micro detection sensitivity parameter.

The K-LD7 features four digital outputs which can directly be used without the need of an MCU. The digital outputs are per default configured in the following way:
Table 2: Default digital output description Pin. No. Name Config Description 2 6 7 8 Digital out 0 Detection Digital detection output. Goes to high if the detection algorithm finds a target in front of the sensor thatisinthe range up to 5m. Digital out 1 Direction This pin signals the direction of the detected target. Digital out 2 Angle This pin signals if the angle of the detected target is on the left or right side of the sensor. Digital out 3 Range This pin signals if the distance of the detected target is in the near field of the sensor. Low backward/receding movement High forward/approaching movement This output is only valid together with a high on pin 2 Low Target on the left side High Target on the right side This output is only valid together with a high on pin 2 Low Target distance higher than 1m High Target distance lower than 1m This output is only valid together with a high on pin 2 With these settings it is easy to use the sensor stand-alone as a distance triggered movement de-
tector with direction recognition, near field option and including the information if the detection was on the left or right side of the sensor. All these settings can be also adjusted by the user as described in the next chapters. The K-LD7 can also be factory configured withyour settings. Contact RFbeam for more information. Host driven operation With a connection of the serial interface to a host
(for example MCU or PC) it is possible to read out thecomplete processing data (RADC, RFFT, PDAT, TDAT and DDAT) and control all the parameters ofthesensor. This is the recommended use case and allows the user to optimize the sensor easily for different applications. The use of the highest baud rate is only recom-
mended to read out data intensive messages like the RADC and RFFT package.

Fora lower maximal speed range the speed resolu-
tion is better and the current consumption is smaller but if the speed of a measured target is higher than the current speed range setting it can generate wrong measurements. Therefore it is very important to set the speed range to a setting where targets are expected. Table 4: Speed range settings Max. speed

12.5 25 50 100 0.1 0.2 0.4 0.8 229 114 57 29 23 27 34 48 An approach to work with a lower maximum speed is to change the sensor orientation to get a field of view without moving objects above the maximal speed range or to increase the threshold offset (described in the chapter Threshold offset on page 10) to reduce the sensitivity of the sensor. To read out data intensive messages RADC and RFFT it is recommended to work with the highest baud rate. If the readout time of the requested data is higher than the typ. frame duration it is not possible to read out the frames in real time. By checking the fra-
me number in the DONE message it is pos-
sible to validate real time readout. Radar settings Speed range The K-LD7 features different parameters to adjust the functionality of the sensor to the needs of different applications. All parameters are stored in the radar parameter structure which can be read and write over the serial interface. The structure and serial protocol is described in the chapter Instruction Set Description on page 13. It is very important to set the distance and speed ran-
ge settings to values that match with the distance and speed of the expected targets in the detection area of the sensor. For example, if the goal is to measure people in the 10m distance range and 25km/h speed range, but cars are moving at 30m with 70km/h, the 100m dis-
tance range and 100km/h speed range setting must be used or the threshold offset needs to be increa-
sed until the cars are no longer displayed in the raw targets. Wrong settings can generate false sensor out-
puts. It is possible that strong targets outside the configured distance or speed range can create false reflections. Distance range The distance range parameter defines the maximum unambiguous distance measurement of the sensor. For a lower maximal distance range the range resolu-
tion is better but if the distance of a measured target is higher than the current distance range setting it can generate wrong measurements. Therefore it is very important to set the distance range to a setting where targets are expected. Table 3: Distance range settings Max. range [m]

scribed in the chapter Threshold offset on page 10) to reduce the sensitivity of the sensor. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 9 / 23 Threshold offset The threshold offset is adjustable and defines the distance in dB between the noise floor of the raw FFT data and the threshold line. The processing in the K-LD7 searches for raw targets that are above this threshold line. The smaller the offset the more raw targets will be found by the processing and the more sensitive the sensor will be. A higher offset will reduce the sensitivity and the number of raw targets. Figure 9: Low vs. high threshold offset The filter can only track one target up to a dis-
tance of 30m. Standard filter type to track different targets like persons or cars Enables a faster detection of the target with the disadvantage to reduce the immunity against reflexions and other interferences. Filter with a high immunity against interferences and a high prediction of temporary lost targets Tracking and vibration suppression The tracking filter features three different filter types and an adjustable vibration suppression. The filter type and the strength of vibration suppression can be selected via the instruction set. With the vibration suppression, it is possible to more or less suppress targets that change their direction quickly, with the disadvantage that it takes more time to detect a target. Table 5: Tracking filter types Filter type Description Standard Fast detection Long visibility Base frequency There are three channels available to adjust the base transmit frequency of the sensor. This can be use-
ful if multiple sensors are transmitting in the same area with the same base frequency to suppress the generated interferences that can occur in such an environment. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 10 / 23 Detection settings Detection filter The last processing step in the K-LD7 generates a detection output based on a set of adjustable para-
meters. The information about the detection is avai-
lable in the DDAT structure or on the digital outputs. The parameters are all located in the radar parameter structure which is described in detail in chapter Para-
meter structure on page 17. Affected data packets Description Table 6: Detection filter parameters Parameter name Min. / max. detection distance DDAT Min. / max. detection angle DDAT Min. / max. detection speed PDAT, TDAT, DDAT Detection direction PDAT, TDAT, DDAT Range threshold DDAT Angle threshold DDAT Speed threshold DDAT The detection area of the sensor can easily be limited with these parameters and allow the user to generate very specific detections without the need of an advan-
ced signal processing. Figure 10: Detection filter visualisation Used to limit the detection area to a minimum and maximum distance. Detection is only generated if the distance of the target isbetween the minimum and maximum detection distance limit. Used to limit the detection area to a minimum and maximum angle. Detection is only generated if the angle of the target is between the minimum and maximum detection angle limit. Used to filter out slow or fast targets. Detection is only generated if the speed of the target is between the minimum and maximum detection speed limit. Used to limit the detection by the direction. It is possible to detect only approaching or receding targets or to allow both directions. Used to define a threshold for the range flag in the DDAT structure. Target distance > range threshold DDAT range flag goes to low Target distance < range threshold DDAT range flag goes to high. Used to define a threshold for the angle flag in the DDAT structure. Target angle < angle threshold DDAT angle flag goes to low Target angle > angle threshold DDAT angle flag goes to high. Used to define a threshold for the speed flag in the DDAT structure. Target speed < speed threshold DDAT speed flag goes to low Target speed > speed threshold DDAT speed flag goes to high. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 11 / 23 Digital outputs The sensor features four digital outputs to signal detection. The digital output 0 always signals if there was a valid detection. The function of the outputs 1 to 3 is configurable over the radar parameter structure. It is possible to route the values of the detection data structure DDAT to these outputs. Table 7: Routable functions for digital outputs 1 to 3 Function Direction Description Signals the direction of the detected target. Low Backward/receding movement High Forward/approaching movement Angle Signals if the angle of the detected target is below or above the angle threshold parameter. Range Signals if the distance of the detected target is below or above the range threshold parameter. Speed Signals if the speed of the detected target is below or above the speed threshold parameter. This output is only valid together with a valid detection Low Angle is below the angle threshold High Angle is above the angle threshold This output is only valid together with a valid detection Low Distance is above the range threshold High Distance is below the range threshold This output is only valid together with a valid detection Low Speed is below the speed threshold High Speed is above the speed threshold This output is only valid together with a valid detection Micro detection The micro detection indicates if there is a very slow movement in the front of the sensor. It is independent from the detection filter and described in detail in the chapter Micro detection on page 7. Hold time and micro detection retrigger The time how long the detection output stays activa-
ted after the last valid detection can be adjusted with the hold time parameter. Furthermore, it is possible to retrigger the detection algorithm using the micro detection feature (see pa-
rameter micro detection in the parameter structure). If this feature is enabled, the detection algorithm first requires a valid detection and then, if there was a valid micro detection, it will retrigger the hold time. If the hold time has elapsed because there was no detec-
tion or micro detection, the detection goes to low and needs again a valid detection before the micro detection is used to retrigger the hold time. If the micro detection retrigger feature is enabled and there is a constant small mo-
vement in the front of the sensor it will ret-
rigger the hold time continuously.

(Host) The server starts up with a default baud rate of 115200 baud. The client has to establish a connec-
tion with the INIT command and has to set the baud rate for the connection. After acknowledging of the INIT command the server changes to the selected baud rate. To disconnect, the GBYE command has to be sent by the client. After acknowledging the GBYE message the server changes back to his default baud rate. Every command sent by the client is acknowledged by the server with a response message (RESP). The response message includes information data about the success or failure of the received command.

mand. But there is also the possibility to set all para-
meter together within a parameter structure or read this structure out. Please refer to chapter Parameter structure for detailed description of the parameter structure. Data output Figure 14: Data output Server

dome (short for radar dome) to protect it from environ-
mental influences or to simply integrate it in the case of the end product. A radar sensor can see trough diffe-
rent types of plastic and glass of any colour as long as it is not metallized. This allows for a very flexible design of the housing as long as the rules below are observed. Cover must not be metallic. No plastic coating with colors containing metallic or Distance between cover and front of Radar sensor carbon particles. should be >= 6.2mm Cover thickness is very important and depends on the used material. Examples can be found in the application note AN-03-Radome. Vibrations of the Radar antenna relatively to the cover should be avoided, because this generates signals that can trigger the output. The cover material can act as a lens and focus or disperse the transmitted waves. Use a constant material thickness within the area used for trans-
mission to minimize the effect of the radome to the radiated antenna pattern. Detailed information about the calculati-
on and thickness for different cover mate-
rials can be found in the application note AN-03-Radome. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 20 / 23 United States (FCC) and Canada (ISED) This module has been granted modular approval for fixed and/or mobile applications by FCC and ISED. Testing for the modular approval has been performed with the 10m range setting for all available frequency channels which represents the maximum TX emission configuration with the complete used bandwidth. This setup can easily be used by the customer for certifi-
cation purposes. This module meets the title 47 of the Code of Federal Regulations, part 15 section 15.249 for intentional radiators operating in the 24.00 to 24.25 GHz band. Labelling and user information requirements RF Exposure Modification to this product will void the users authority to operate this equipment. The OEM integrator is responsible for the fi-
nal compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The radiated output power of the device is far below the FCC radio frequency exposure limits. Neverthe-
less, the device should be used in such a manner that the potential for human contact during normal operation is minimized. If the label of the module is not visible from the outs-
ide of the end product, it must include the following texts on the label of the host product:
FCC Contains FCC ID: 2ASYV-K-LD7 ISED Contains IC: 24358-KLD7 In addition to marking the product with the appro-
priate IDs, the end product shall bear the following statement in a conspicuous location on the label or alternatively in the user manual:
This device complies with Part 15 of the FCC Rules and with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must ac-
cept any interference received, including interferen-
ce that may cause undesired operation. Le prsent appareil est conforme aux CNR dIn-
dustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes: (1) lappareil ne doit pas produire de brouillage, et (2) lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 21 / 23 An OEM integrator can show compliance to article 3.1(a) and 3.1(b) for the final product by doing internal or external tests and following the Module A (Annex II of the RED) assessment procedure. To show com-
pliance against article 3.2 it is possible to reuse the assessment of the K-LD7 as long as it is the only ra-
dio module in the final product or if the integrator can guarantee that only one radio module is operating at the same time. Test reports of the K-LD7 are available on request. The ETSI guide EG 203 367 provides de-
tailed guidance on the application of harmo-
nized standards to multi-radio and combined equipment to demonstrate conformity. RF Exposure Information (MPE) This device has been tested and meets applicable limits for Radio Frequency (RF) exposure. A detailed calculation to show compliance to the RED Article 3.1(a) is available on request. Simplified DoC Statement Hereby, RFbeam Microwave GmbH declares that the radio equipment type K-LD7 is in compliance with Directive 2014/53/EU. The declaration of conformity may be consulted at www.rfbeam.ch. Europe (CE-RED) This module is a Radio Equipment Directive assessed radio module that is CE complaint and have been manufactured and tested with the intention of being integrated into a final product. According to the RED every final product that inclu-
des a radio module is also a radio product which falls under the scope of the RED. This means that OEM and host manufacturers are ultimately responsible for the compliance of the host and the module. The final product must be reassessed against all of the essenti-
al requirements of the RED before it can be placed on the EU market. This includes reassessing the module for compliance against the following RED articles:
Article 3.1( a ) : Health and safety Article 3.1( b ) : Electromagnetic compatibility ( EMC ) Article 3.2 :
Efficient use of radio spectrum ( RF ) The RED knows different conformity assessment procedures to show compliance against the essential requirements (See RED Guide, chapter 2.6b). As long as the radio module can show compliance to Article 3.2 by the use of a harmonized standard, which is listed in the official journal of the EU (OJEU), it is not necessary to do an EU type examination for the final radio product by a notified body. In this case it is possible to demonstrate conformity according to the essential requirements of the RED by using Module A
(Annex II of the RED), which allows to show conformi-
ty by internal production control. As long as a harmonized standard listed in the OJEU can be used to demonstrate con-
formity in accordance with Article 3.2 of the RED, it is possible to carry out the CE certi-
fication in self-declaration without the invol-
vement of a notified body. The K-LD7 shows compliance against the Article 3.2 by the use of the standard EN 300 440 which is a harmonized standard listed in the OJEU, what gives the possibility to show conformity by internal produc-
tion control. RFbeam Microwave GmbH | Schuppisstrasse 7 | CH-9016 St. Gallen | www.rfbeam.ch | K-LD7 | data sheet 12/2020 - Revision B Page 22 / 23 O U T L I N E D I M E N S I O N S Figure 20: Outline dimensions in millimetre 5
