The radar is able to track up to ten target signals in either approaching or receding directions (limited to 5 targets in each direction when using bi-directional mode). The 317 radar is a frequency modulated continuous wave, FMCW, radar that operates in the 24GHz band. KEY FEATURES Speed measurement from 12kph to 300kph across multiple lanes Target range measurement from 6-70 metres Can discriminate between approaching and receding traffic Custom designed planar antenna Ease of integration to host system High speed RS422 serial communications to host equipment Hardware target simulation built into the radar 3 INTRODUCTION TYPICAL APPLICATIONS Speed enforcement radar traffic detection - receding Speed enforcement radar traffic detection - receding PRODUCT OVERVIEW Indicator LED Mounting points Data connector 4 RADAR CHARACTERISTICS The radar has been designed to have a specific set of functional characteristics which make it suitable for range
& speed measurements of multiple targets. RADAR ANTENNA The antenna design is a planar patch array with the following performance;

-3dB Plane Polarised OPERATING FREQUENCY BAND AND POWER The transmitter is interlocked as a closed loop system with the hardware processor. This enables full monitoring of the transmitter frequency which ensures the transmission remains in the intended transmission band. The design confidence means that the nominal centre frequency of the transmission shall remain within a 10MHz window for the required 7 years for a radar functioning normally. The change in frequency with temperature is measured to be <140KHz/C The radar frequency and power is as follows;
Parameter Centre Frequency Frequency Modulation Power Field Strength ITU Code Specified 24.125 GHz 44MHz
<100mW eirp Typically 750m V/m 44M0FXN Notes At 3m 5 RADAR CHARACTERISTICS FREQUENCY MODULATION The radar is an FMCW radar where the Frequency Modulation (FM) characteristics give the radar a transmit bandwidth of 44MHz. The FM is such that it is symmetric about the centre frequency of the band it is operating in. The change in transmit bandwidth with temperature is measured to be typically 30KHz/C. The stability of the bandwidth over time is anticipated being better than 3% in the first year and lower for each subsequent year. Bandwidth control over temperature The bandwidth control over temperature (44MHz at 24.125GHz) has been specifically designed to minimise any range error over the working temperature range. This performance ensures correct range to target measurement of the radar under the operating conditions. The following graph illustrates the performance of a typical unit over the temperature range of -30 to +60 degrees.

The range performance of the 317 is tested at manufacture by simulation over the range 6 to 70m. Range Measurement The range resolution is largely a function of the bandwidth. The range is reported in units of metres. The range of a target is reported to the nearest 0.1m. The range accuracy of any particular measurement is dependent on the signal to noise ratio of the received signals. These can vary by a large amount. Speed Measurement The speed measurement is fully instrumented over the range 12 to 300km/hr in both directions. The speed measurement is reported to the nearest 0.1km/hr and is corrected for the 22 mounting angle as its default setting. The angle can be adjusted with the appropriate command. The speed is reported in Km/hr and there is an option to convert the speed reading to mph with the appropriate command. Frame Rate The frame rate of the radar is the rate at which the radar takes speed and range measurements, it is fixed at 48 frames/sec. Typical Radar Output The following image shows the typical output from the 317 displaying the Target detect and Heart-beat messages. 7 INSTALLATION RADAR INSTALLATION & ALIGNMENT For best detection performance the radar must be setup correctly. Failure to do so can result in inaccurate or false detections. System Integration The AGD317-105 has been designed to be used in conjunction with the AGD340 and a host system. It is the responsibility of the supplier of the host system to ensure that data fusion \ correlation of the speed and range data from the AGD317-105 and speed data from the AGD340 is done in such a manner as to be fit for purpose. Radar Mounting Angle Radars are supplied factory programmed to be used for a specific mounting angle, usually to 22 degrees. This angle is the angle the radar points across the road from the direction of the road (see diagram). The command *ANGLE may be used to query or set the angle. This angle is used by the radar to adjust the speed the radar measures to the actual target speed and therefore it is important the radar is setup with the correct angle. If the radar is setup with an angle that is less than the mounting angle then the radar will measure speeds that are larger than the vehicles true speed, while if the angle is greater than the mounting angle the radar will measure speeds that are less than the vehicles true speed. The radar transmits a radio beam across the road that has a horizontal beam width of
~7 degrees. The vertical beam width of the radar beam is relatively large at 28degrees so although the radar should be made level this is not crucial for correct operation. For a fixed camera installation often the radar is mounted relatively high (~3m) and in this case it is desirable to point the radar more down towards the ground. In this application careful consideration of the radar beam and its shape is required to ensure that all the lanes of the road are covered. 317 Beam Analysis Mounting Height: 4m Mounting Angle: 7.5 below horizontal Targets: vehicle reflection assumed from a height of 1m Mounting Height The radar should be mounted at a height of between 1 and 3 metres. Mounting at a height >3 metres is not precluded dependant on the minimum offset adopted. 8 Typical 65m70m5m3.5m3.5m3.5m26m3.5m3.5m2273.5m SYSTEM HARDWARE OVERVIEW SYSTEM HARDWARE OVERVIEW Target Simulator Microwave Transceiver Amplifiers
& Signal Conditioning Modulation Analogue to Digital Converter RS422 Digital Signal Processor 9 SYSTEM HARDWARE OVERVIEW RS422 SERIAL INTERFACE A UART interface is provided that uses RS422 voltage levels on the communications connector. At power-on a Boot-loader program is executed and uses a fixed Baud rate of 115200,N,8,1. The Boot-loader executes the main application code which uses a default baud rate for of 460800 8 data bits with odd parity. The Baud rate of the application code may be changed using the *BAUD command to speeds of up to 921600. The baud rate settings are saved into non-volatile memory of the radar ready for the next time the radar is powered on. The serial interface default setup during normal operation is shown in the table below.

+12v DC n/c n/c Power supply The radar is powered using a DC voltage in the range of 10.8 to 16 Volts. At 12V the current consumption of the radar is typically 225mA. Reverse polarity protection is included in the design. The radar can take a large current during power up that is of the order of amps which only lasts for ~1ms and as such should not affect most applications. A thermal fuse with a 750mA rating has been installed to protect against electrical short circuit fault conditions. 11 SOFTWARE FUNCTIONALITY OVERVIEW At power-on the 317 radar executes a Boot-loader program which communicates at a fixed Baud rate of 115200, no parity, 8 data bits and 1 stop bit over the RS422 interface. The Boot-loader provides facilities for erasing the Flash and updating the firmware. The 317 radar uses a real time operating system and is continuously performing a number of tasks simultaneously using a time multiplexing method. The Boot-loader and the main data capture processing task flow diagram are shown below.

These are sent over the RS422 UART link. Commands are immediately followed by an operator that indicates the required action. Not all operators are supported for all commands. Where an operator is used and it is not supported the radar will respond with a warning message. The table shows the operators that are used by the radar. Operator Operation
Set something to a value e.g. *DIR=A<CR> sets detect direction to approaching Respond with value or values Set default value for parameter Provide help on the command e.g. *DIR$<CR>
Do something e.g. *REBOOT! Reboots the radar Command Operators Where a command is used to enquire or set a radar parameter the radar will respond in a set way. The radar will respond with a hash, #, followed by the command name, operator used and then the value of parameter or parameters. For example
*DIR=A<CR>
Radar responds with #DIR=A<CR>
*DIR?<CR>
Radar responds with #DIR?A<CR>
Checksum Calculation The unsolicited messages and the Serial Number output by the 317 contain a checksum. The checksum is performed as an exclusive OR (XOR) sum of each of the characters in the message excluding the header and termination characters. The checksum is then appended to the message as a 2 character hexadecimal number. e.g. Consider a Heartbeat message prior to the header and termination HB,0000133*
H = 0x48 B = 0x42 An XOR operation on these two characters results in 0x0A which is then used in the XOR with the next character
(, = 0x2C) and so on until all of the characters have been summed. The result is appended to the message following the * character and the message is transmitted with the STX and ETX characters.

*TS COMMAND & HARDWARE SELF-TEST The radar has a built in hardware based target simulator. This command is used to perform a self-test using this built in target simulation hardware. There are twelve targets that maybe simulated in either receding or approaching directions The format of the command is: *TS=<Target Number>,<Direction><CR>

*TS COMMAND & HARDWARE SELF-TEST (CONTINUED) When in Advance Mode the radar will only accept and report simulated targets that are advancing. If a recede simulated target is requested the radar processing will reject the target as wrong direction and only the
#TS:COMPLETE<CR>
message will be sent as confirmation that the simulation has been completed. When in Recede mode vice versa. It is recommended that the system uses the following pass/fail criteria for acceptance to specification for a radar self-test. It is also recommended that after power-up of the radar, the host system calls the radar self-test function to simulate at least one approaching and one receding target. When in Bi-Directional mode the radar will report both advancing and receding simulated targets. Parameter Direction Speed Target Range Target Amplitude Checksum Pass Criteria 100% correct 1.0mph 1.0m N/A 100% correct The hardware target simulator is fully independent of the radar measurement system. This is used to verify the operation of the radars measurement circuitry. The self-test does NOT operate automatically on power-up of the radar. During simulation the microwave front end is disconnected from the ADC to avoid any possible interference with the simulation. The radar self-test function can be called at any time using the *TS command. The *TS command calls a pre-loaded simulated test target condition. There is a selection of pre-loaded test target conditions as set out. To distinguish real targets from simulated targets the radar inserts an X or a Y in the direction fields of all related messages produced. 16 MESSAGE FORMATS TARGET DETECT MESSAGE Target Detect Message This message is sent after the radar has established that a vehicle has entered the radars beam.

The transmission characteristics of low power radio devices is a highly regulated environment for the assurance of safe use. There are strict limits on continuous emission power levels and these are reflected in the testing specifications that the products are approved to. These type approval limits are reflected in the product specifications required for a typical geographic area such as those for the EU (ETS300:440), for the USA (FCC part 15c) and for Australia/
New Zealand (AS/NZS 4268). The limits adopted in these specifications are typically replicated in many other localized specifications. The level of safe human exposure to radio transmission is given by the generally accepted guidelines issued by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). This body has issued guidance for limiting exposure to time-varying electric, magnetic and electromagnetic fields (up to 300 GHz) which are quoted below.

Note that a theoretical max level at a 5cm distance (which gives 0.318mW/cm2) is at a point in the field where the radar beam is not properly formed. Note 4 Comparison for product model 317 operating in the band typically 24.050GHz to 24.250GHz From the table it can be seen that it is extremely unlikely that a potentially hazardous situation could occur owing to the use of such low power devices. It is considered to be good practice not to subject humans to radiation levels higher than is necessary. In a works environment where multiple equipment on soak test are to be encountered then it is considered good practice to contain the equipment in an appropriate enclosure lined with radar absorbing material. 29 CERTIFICATION NOTES DISCLAIMER While we (AGD Systems) endeavour to keep the information in this manual correct at the time of print, we make no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with respect to the information, products, services, or related graphics contained herein for any purpose.
