Question Solutions
The Radar does not
work after being
powered on
1) Check power connection and voltage
2) Check whether the positive and negative electrodes of power module
are correctly connected
3) Check communication cable connection
4) Check the data receive interface, or the software can work properly
5) Check the serial port settings of the program
Messy code
1) Check communication cable connection
2) Check baud rate settings
3) Check EMC/EMI
The Radar does not
capture targets
1) Check the elevation angle and the azimuth angle of the Radar. Make
sure that the area to be detected is fully covered by the radar beam
2) Compare the animation and the real trajectory of the vehicles
3) Check whether the capture distance is reasonable
4) Check whether the threshold is set too high
Vehicles are not
captured
1) Check whether there are strong EMI source around the Radar
2) Check the elevation angle and the azimuth angle of the Radar. Make
sure that the area to be detected is fully covered by the radar beam
3) Check whether the threshold is set too high
Missed capture
1) Check the elevation angle and the azimuth angle of the Radar. Make
sure that the area to be detected is fully covered by the radar beam
2) Compare the animation and the real trajectory of the vehicles
3) Check whether the capture distance is reasonable
4) Check whether the threshold is set too low
