AWR1642: Clutter removal

Greg Ratzel

Part Number: AWR1642

I see in the v1.1.0.2 SDK source code there is a "clutterRemoval" option for the mmw CLI.  Can you please explain if this feature is functional and what algorithm it uses?

    Hi Greg. 

    The algorithm assumes that the Radar is stationary, and the scene for most part is also stationary. In other words, clutter is static.  In a frame, we compute the average chirp and remove it prior to further processing. This removes all static objects from the frame. 

    Attached is the relevant portion from the SDK's userguide.

    Regards
