Radar waveform The ScanBrick W system transmits a FMCW signal in automotive band. At receiver stage, matched filtering is performed via a mixing stage of received signal with a copy of the transmitted one. Such an operations, also known as dechirping provides an IF signal which frequency components are directly related to the targets distance. The signal is sampled and sent to host via Ethernet link.

Introduction to ScanBrick W Radar The ScanBrick W system is a FMCW MIMO radar which transmit a frequency modulated signal continuously in order to measure range as well as angle and velocity. This differs from traditional pulsed-radar systems, which transmit short pulses periodically. FMCW radars uses short (millimeter) wavelength signals, which enables detection of objects with sub-millimeter accuracy. It can also penetrate materials like plastic, drywall, and clothing while maintaining its high level of performance despite harsh environmental conditions such as rain, fog, dust and snow. The size of system components such as the antennas required to process mmWave signals is small. An mmWave system operating at 7781 GHz (with a corresponding wavelength of about 4 mm), will have the ability to detect movements that are as small as a fraction of a millimeter. An FMCW radar system transmits a chirp signal and captures the signals reflected by objects in its path. A chirp is a sinusoid whose frequency increases linearly with time as shown in the frequency vs time plot. A chirp is characterized by a start frequency fc, bandwidth (B), and duration (Tc). Slope of the chirp defines the rate at which the chirp ramps up. In the figure, chirp is sweeping a bandwidth of 4GHz in 40s which corresponds to a slope of 100MHz/s. Figure 1: Chirp signal, with amplitude as a function of time Figure 2: Chirp signal, with frequency as a function of time 6 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 1.5.2. RF specification RF board consists of single-chip FMCW transceiver capable of operation in the 77- to 81-GHz band. It is an ideal solution for low power, self-monitored, ultra-accurate radar systems. It consists of 3TX, 4RX system with built-in PLL and ADC converters. The RF subsystem includes synthesizer, PA, LNA, mixer, IF, and ADC. This subsystem also includes the crystal oscillator and temperature sensors. The three transmit channels can be operated simultaneously for transmit beamforming purpose as required; whereas the four receive channels can all be operated simultaneously. Figure 4: ScanbrickW43 antenna layout Figure 3: Virtual antennas position The transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. A maximum of two transmit chains can be operational at the same time, however all three chains can be operated together in a time-multiplexed fashion. Each transmit chain can deliver a maximum of 13 dBm at the antenna port on the PCB. The receive subsystem consists of four parallel channels. A single receive channel consists of an LNA, mixer, IF filtering, ADC conversion and decimation. All four receive channels can be operational at the same time. ScanBrick W support continuous acquisition mode with frequency modulation (FMCW modulation type). 1.5.3. Applications ScanBrick W radar is a Tank Level Probing Radar (TLPR) system. 7 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 2. Mechanical interface and installation 2.1.

Operational state In this state both the Radar task and the on-board processing task are activated. The system is now ready to receive/send commands/data from/to a connected host (see Section 4.2). Notice that in this state the system is still able to receive maintenance commands. NOTE:
Host/Server software libraries for communication are closed and not accessible to any user. In case of need of a firmware update, the new image is crypted and protected against unauthorized individuals. 14 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 4. Level Metering SW Application Level Metering SW is released as a dynamic-link library, LevelMeterCLI.dll, developed in C++/CLI. The interface of such a library is detailed in ARE-011967. In order to test this library, LeverMeterGUI application (C# developed) has been released. Here below a guide to this application is provided. 4.1. Installation Requirements The recommended minimum system requirements for a proper use of LevelMeterGUI software are:
Intel Core i5 5300U vPro Processor
- Microsoft Windows 7/ Windows 10
Intel HD 5500 graphics
- 8GB RAM In order to connect to ScanBrick W system for a new data acquiring session, a Network Ethernet cards (100Mbit/s) is necessary. Procedure To install LevelMeterGUI, it is first important to have no previous version of the software installed. If this is the case, make sure to remove it from the computer before installing the current version. Open Explorer and go into the LevelMeterGUI setup folder. The content of the folder should be as shown in Fig.5. 15 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.5 LevelMeterGUI Setup Folder From the folder, click on setup.exe to start the setup procedure. A dialog will appear, asking to install the .Net Framework 4.5, if not already installed on your PC. Click Install. Once the .Net Framework has been installed, the actual LevelMeterGUI installer will appear (see Fig.6). Click Next for the following three screens, selecting if needed a different destination folder for the software. Once the installation is complete, click on Close. 16 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.6 LevelMeterGUI Setup Wizard 4.2. Working Mode When opening LevelMeterGUI (for example by clicking on the shortcut created on the Desktop by the installation procedure), the window in Fig.7 will appear. 17 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.7 LevelMeterGUI Main Window Device Selection First thing to do to have the application working is to select a device using the panel in Fig.8. By clicking Get All button, a list of all the radar system on the network will be provided in the drop-
down menu labeled as Device IP / MAC. For each device, both the IP and the MAC addresses will be reported. Click on one of the devices in the menu to fill the text boxes IP Address and MAC Address (which can be also manually edited). NOTE: if a device in the network is already connected to another host application instance (i.e. it is in a busy state), its address will appear red colored in the Device IP / MAC drop-down menu and it will be impossible to select it. Since the radar can be connected to one and only one application at a time, it is impossible to connect to a device already busy. Once the addresses text boxes are filled, two alternative choices are available:
- Press Select IP button: in this case the Level Metering application will always work with the radar device owner of this IP address. If the connection with the device is lost during a working session (for example due to a network brake down), the Level Metering application will retry 18 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 to connect with this IP address. If this button is pressed, the Device Connection Panel is updated as in Fig.8.
- Press Select MAC button: in this case the Level Metering application will always work with the radar device identified by this MAC address. In case of connection break down, the application will try to reconnect with this MAC address, no matter of the IP which is currently assigned to the device. If this button is pressed, the Device Connection Panel is updated as in Fig.8. Fig.8 Device Selection Panel The button Browse is useful to select the folder of the filesystem where to store all the data, logs and results of the application. LevelMetetrGUI application will set the content of the folder as shown in Fig.9. The results of the application processing are stored in separated folders, one for each working day (see the folder 2019.10.01 in Fig.9). In the Debug folder, for each working device, these data are stored:
- Last set radar configuration;
- Log files;
- Raw Data (i.e. data produced by the radar and not processed);
- Some processing results. To reduce the amount of stored data, it is necessary to uncheck the Enable Debug check box: in such a way, the logs only will be saved in the Debug folder. 19 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Device Connection Fig.9 Data Folder Depending on the selected device, the Connection management panel will appear as in Fig.10 (IP address has been selected) or in Fig.11 (MAC address has been selected). Fig.10 Connection to an IP Address Fig.11 Connection to a MAC Address To manage the connection with the device, three buttons are available:
20 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022
- TryConnect button: by clicking this button, a cycle of period connection attempts is started. Each time the device disconnected, automatically the application will try to reconnect the system. When a connection attempt succeeds the Connection State of the Level Metering application (see Fig.14) becomes CONNECTED, elsewhere it is DISCONNECTED.
- Disconnect button: by clicking this button the periodic connection attempts are stopped and the application disconnects from the radar (the Connection State is forced to DISCONNECTED in Fig.14).
- Maintenance button: by clicking this button, the radar system maintenance window can be accessed (see Section 4.3). This button can be clicked only if TryConnect button has not been previously clicked (the system must be disconnected). Configuration Before starting a data acquisition session, it is necessary to configure both the acquisition and the data processing, using the panel in Fig.12. Fig.12 Configuration Panels To configure the acquisition, use the Acquisition Configuration panel:
21 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022
- Acquisition Mode: this is a drop-down menu to select the measure type. Available options are: 1D (the system returns just one level measure), 2D (the system returns level measures on a 1D grid) or 3D (the system returns level measures on a 2D grid).
- Acquisition Speed: this is a drop-down menu allowing the selection of the rate of the radar acquisition and hence, the frequency of level meter results updates. Three speed levels are available: LOW (acquisition rate approximately of 13 Hz), MEDIUM (acquisition rate approximately of 103 Hz) and HIGH (acquisition rate approximately of 188 Hz).
- Min. Range / Max. Range / Min. Phi / Max. Phi / Min. Theta / Max. Theta: these are minimum and maximum values of distance, azimuth angle and elevation angle within which the level survey must be limited. If 1D Acquisition Mode has been selected, only the minimum and maximum range are used by the application; if 2D acquisition is set, both range and theta limits are used. Finally, all the limits are necessary if the 3D acquisition mode has been selected. By clicking the Configure button, the acquisition is configured and the Acquisition State of the application goes from READY to CONFIGURED (see Fig.14). The acquisition configuration can be set as many time as required, provided that the system is not already acquiring (in such a case, stop the acquisition to update the configuration). To configure the level meter processing, use the Processing Settings panel:
- Obstacle Cancelation: Enable or disable obstacles effect cancelation. When the obstacles cancelation is enabled, the effect of obstacles (for example, the contribution of the edge of the ladle) is removed by the level meter processing. TIP: uncheck this flag when performing level metering tests in an office environment, if you want to measure the distance of a not moving target (for example a wall).
- Acquisition Average: Set an average factor for the acquisition repetition frequency (i.e. the radar pulse repetition frequency). Measure update frequency (i.e. the frequency for the level measure refresh) will be given by the radar pulse repetition frequency (set by selecting an Acquisition speed value in the Acquisition Configuration panel), divided by this value. 22 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022
- Process Average Window: Set temporal windows length (expressed in seconds) used by the level meter processing to carry out some internal averages. This factor does not affect measure update frequency (i.e. the frequency for the level measure refresh).
- Statistics Window: Set the width (expressed in seconds) of the window for statistics purpose. Statistics is used by level meter processing and its strictly related to the computation of the standard deviation of the measured level. Finally, by accessing the Displayed Level panel some display configurations can be set:
- Level Type: this drop-down menu allows to select the type of returned level measure (both saved in the results file and displayed in the data visualization panel, Fig.15). It is possible to select FIRST RETURN (the level value corresponding to the 90% statistic percentile, computed from the maximum range distance), PEAK (the level value corresponding to the statistics mode) and MEAN (the level value corresponding to the statistics mean).
- Threshold: this is a constant target level value, drawn in Fig.15, to have a baseline against which to compare the real-time measured value. Acquisition Management Click the button Start Acquisition in the Acquisition Panel to start data acquisition and processing. This button can be clicked if and only if the Acquisition State of the application (see Fig.14) is CONFIGURED. If the starting operation succeeds, this state becomes ACQUIRING and new data and results will be saved in the folder set in the Results Folder text box (see Fig.8) and displayed in the Data Visualization panel (see Fig.15). Fig.13 Acquisition Commands Panel By clicking the Stop Acquisition button, the radar acquisition is stopped and the Acquisition State of the application (Fig.14) goes back to CONFIGURED. 23 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 State Visualization The State Panel allows to have a complete description of the state of the application:
- Connection State: it can be CONNECT (radar is currently connected to the application) or DISCONNECTED (radar disconnected).
- Acquisition State: it can be READY (acquisition not configured yet), CONFIGURED (the acquisition has been configured at least one time) or ACQUIRING (the system is currently acquiring data and updating measure results).
- Acquisition Rate: is the frequency of the radar (expressed in Hertz) of acquisition of a new data. It depends on the selected Acquisition Speed (see Fig.12).
- Acquired: it is the number of acquired data from the start of the acquisition.
- Missed: it is the number of missed data from the start of the acquisition.
- Accumulated: it is the number of accumulated data, i.e. the number of data received and not processed yet to get a new level measure. If this value increases, this means that the selected data frequency is too high for the application processing (hence it is suggested to reduce the Acquisition Speed or to increase the Acquisition Average, see Fig.12). Fig.14 State Panel Data Visualization When the Acquisition State of the application is in ACQUIRING, the measure results are displayed in the panel of Fig.15. In the upper panel, the grid of measure is displayed: for each point of the (Phi, Theta)-grid the instantaneous measure of distance is reported. 24 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 By clicking on one of the cells of the grid, it is possible to see in the lower panel the time series of the distance measure of the cells (i.e. how this measure change depending on time). Change the number in the Time Interval box to change the number of displayed minutes in the graph. Fig.15 Data Visualization Panels Log Visualization At the bottom of the main window, it is possible to access to all the logs generated by the application, warning if a change in a state of the application or an error occurred. Click Clear button to clear all the logs of the panel. Fig.16 Log Panel 25 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 4.3. System Maintenance Clicking the button Maintenance of the panel in Fig.10 or Fig.11, it is possible to access the System Maintenance windows of Fig.17. Using this window, it is possible to access to the radar maintenance operations, such as:
to get a FW version and update the FW of the radar
to get both the IP and MAC addresses of a radar;
to get and update the network static settings of the radar;
to get and update the radar connection mode;
to get and update the Keep Alive period of the radar (i.e. the period of the messages the radar uses to check if the connection with a host application is still alive). 26 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.17 LeverMeterGUI Maintenance Window System Connection First thing to do to start a system maintenance session, is to connect the device using the Connect button in Fig.18. Note that in this case, just a single synchronous attempt of connection with the radar is performed. If this attempt fails, it is necessary to retry by clicking the button again. Press Disconnect button to disconnect the system. The result of the connection/disconnection operations is displayed in the Connection State box. All the other operations in this maintenance windows can be successfully performed only if the system is connected. 27 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 NOTE: when the maintenance windows is closed, the system will be automatically disconnected. Fig.18 System Maintenance Connection Panel Finally, clicking the Get Address button, it is possible to get the MAC address of the selected device
(or the IP address if the device has been selected using the MACaddress). Connection Mode Using the panel in Fig.19 it is possible to get the current Connection Mode of the radar (i.e. the way by with the radar configure its network board, once it exits from the Recovery State, as explained in 3.2). It is also possible to update such a mode. The possible connection modes are:
1. FACTORY_IP: when exiting the Recovery State, the radar will configure its network board using a static IP address, hard coded in its non-volatile memory. This static IP configuration is set by the producer when the radar is manufactured. 2. STATIC_IP: when exiting the Recovery State, the radar will configure its network board using a static IP address, configurable by the user (Fig.20). 3. DYNAMIC_IP: when exiting the Recovery State, the radar will configure its network board using an IP address gotten from a DHCP server. NOTE: it is necessary to restart the device to have the Connection Mode changes to become effective. 28 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.19 Connection Mode Panel System Network Configuration Using the panel in Fig.20 it is possible to read and update the network static configuration of the radar, i.e. IP address, Network mask and Gateway address. This network static configuration is the one used when STATIC_IP mode is set as Connection Mode for the radar. Fig.20 System Network Static Configuration Panel NOTE: current IP address of the radar (shown in the panel of Fig.18), should not match the static IP address get from the radar in Fig.20. For example, if the currently set Connection Mode (Fig.19) is DYNAMIC_IP, the current IP address of the radar is obtained by a DHCP server and hence it almost certainly does not match the statically configured IP address. NOTE: it is necessary to restart the device to have the Network Static Settings changes to become effective. Keep Alive Period Management Using the panel in Fig.21 it is possible to read and update the period of the keep alive message, expressed as millimeters. This is a message periodically sent from the radar to the host, to check if the connection is still alive. The period of the keep alive message is both the duration between two consecutive message transmissions and the time radar waits for an answer from the host. 29 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.21 Keep Alive Management Panel NOTE: it is necessary to restart the device to have the Keep Alive Period changes to become effective. System Version Panel in Fig.22 allows to read the version (of the FW, FPGA and board) of the radar. Fig.22 System Version Panel System FW Update To update the radar version, it is necessary to access the panel in Fig.23. First, select a FW file provided by the radar producer (a file with .bin extension) by browsing the file system (Browse button). Then click the button Start Transfer and the file transfer will start, as shown in Fig.24. Fig.23 FW Update Panel (update NOT in progress) To stop an in progress transfer, just click on the Stop Transfer. Otherwise, wait until the transfer ended; when this happens, the progress bar achieves the 100% of work done and a dialog box notifies the user. 30 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 Fig.24 FW Update Panel (update in progress) NOTE: as stated by the red label in Fig.24, it is absolutely mandatory NOT to switch off the radar when a transfer operation is in progress. Stop the transfer or wait until it ends before turning off the radar. NOTE: it is necessary to restart the device to have the new updated FW effectively working on the radar. 31 ScanBrick W User Manual Doc: ARE-016631 Issue: 7.2 Date: Sept 2022 5.
