Sufficient information is provided to understand the operation principle, the set up and the tuning of the radar sensor. 2. General information JRC-M's RADAR SENSOR measures the distance, velocity, azimuth and received power corresponding to each target. Such information is to be transformed from the radar, every measuring cycle on the basis of Frequency Modulated Continuous Wave (FMCW). Figure 1 shows a photograph of JRC-M's RADAR SENSOR. Figure 1: JRC-Ms RADAR SENSOR Figure 2 shows a photograph of the main cable (including the power cable and RS-485 full-

duplex communication cable) to be connected to the JRC-M's RADAR SENSOR.

Figure 3: Connection from the JRC-Ms RADAR SENSOR to power supply and communication equipment. 3 / 5 JRC-M's RADAR SENSOR is mounted on an Unmanned Ground Vehicle (UGV) with four wheels (tires) for smart agriculture, as illustrated in Figure 4. JRC-M's RADAR SENSOR is used to prevent the UGV from colliding surrounding obstacles. Figure 4: Image of the concept of JRC-M's RADAR SENSOR 3. JRC-M's RADAR Sensor Component Description JRC-M's RADAR SENSOR consists of the following components:

Plastic molded radome through which the radar beams are emitted. Radio Frequency (RF) Printed Circuit Board (PCB) including the antenna which is placed between the housing and the radome. Power supply wirings and communication wirings inside the housing, connecting the Aluminum housing with waterproof connector for power supply cable and RS-485 full-

PCB and the waterproof connector. duplex communication cable. 4 / 5 4. JRC-Ms RADAR SENSOR Software Operation Only one operational mode is implemented; JRC-M's RADAR SENSOR measures at the regular intervals of FMCW. JRC-M's RADAR SENSOR operates in this mode, as long as the power is supplied by the UGV. 5. Troubleshooting In the normal state of the operation of JRC-M's RADAR SENSOR, the target point cloud packet written with the ASCII codes is transferred every 100 ms to the communication equipment. If you cannot receive the target point cloud packet, first check the following connection:

Main cable and Power supply Main cable and Communication equipment If the connection is correct, restart JRC-M's RADAR SENSOR (turn off the power and then turn on again) and check if you can receive the target point cloud packet. 6. Information to be included in User Manual The following information must be included in the user manual to ensure continued FCC regulatory compliance. Radiofrequency radiation exposure Information:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC RF Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least 20cm or more away from persons body. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. End of Documents 5 / 5
