IWR6843ISK-ODS: Azimuth range heatmap

Hi,

When "Remove Static Clutter" in mmWave Demo Visualizer,  Azimuth-Range Heatmap is stopped.

Could you check what is problem?

Below is my setting.

   - SDK 3.3 version

   - mmWave Demo Visualizer configuration

   - Results

Before "Remove Static Clutter", Azimuth -Range Heatmap looks fine.

    Hello,

    The azimuth range heatmap being shown is the Zero doppler (static) heatmap. 

    When you use static clutter removal you are essentially removing the majority of the static signal. This is why you don't see any information in the azimuth-range heatmap.

    If you look at range-doppler heatmap you should be able to see data related to movement in the scene.

    Hi,

    There are 3 static clutter removal options in SDK.

       - AoAProcDSP_clutterRemoval which called from AoAProcDSP_RangeAzimuthHeatmap

       - AoAProcDSP_clutterRemoval which called from AoAProcDSP_processMultipleVirtualAntennas

       - DPU_DopplerProcDSP_clutterRemoval

    All three are executed by "clutterRemoval" command.

    If there will be no information in azimuth-range heat map when use "clutterRemoval", why AoAProcDSP_clutterRemoval is implemented?

    And when I comment-out DPU_DopplerProcDSP_clutterRemoval function, still I can't see any information in the azimuth-range heat map.

    Could you recommend me how to implement both removing static clutter and seeing information in azimuth-range heat map?

    What are you trying to see in the azimuth range heatmap?

    The azimuth range heatmap is plotting the zero Doppler, Static signal.

    It is not possible to have useful information in that Static azimuth range heatmap and use static clutter removal. You are removing all the static objects from a plot that is supposed to show static objects.
