IWR6843: Detecting non-existent objects directly in front of sensor when moving

Part Number: IWR6843

I am using the OOB demo with the radar mounted about 30cm above the ground on a cart. I'm finding that when moving the radar forward in car-park (ie open flat environment) there are spurious detections of objects in front of the sensor. The seem random and don't appear to have any frame to frame persistence or correlation. As soon as the cart is stationary they disappear. 1-4 detections will appear a couple of cm infront of the sensor every couple of frames. I've tried decreasing the cfar threshold but that wasn't useful.

    Hello,

    Please provide the view of the plot and the setup to spot the possibilities of objects in scene that may cause reflection.

    If possible please get the 3D location, velocity and SNR of the 'false' objects to understand what kind of reflection is strong enough to be detected as object.

    Thank you,
