AWR1642BOOST-ODS: What are these objects showing in visualizer?

Expert 2050 points
Part Number: AWR1642BOOST-ODS

I did some tests using AWR1642BOOST-ODS. The radar sensor was placed in open area and the obstacles are put in front of sensor a few meters away. I can see the visualizer shows the detected obstacles, that is great.

But I also found there are always some objects are detected by radar sensor, the objects are less than one meter away from sensor. Their positions are basically the same even if I change the direction. Please refer to below picture. The obejcts highlighted in orange circle. are these objects on the sensor board itself? How can we ignore them in realistic application?

  • HI,

    These could be reflections from the ground.

    Depending on the application, there is need for a detection algorithm.

    For example, if the reflections such as R<1m are of no interest they could be removed.

    thank you
