IWR6843AOPEVM: No Cloud Points when people are not moving

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843AOP

Tool/software:

We are working with IWR6843AOP evaluation module.

We are using:

  • Radar Toolbox - 2.30.00.12
  • 3D People Tracking Example

Problem:

  • When people stop to move, the cloud points provide by UART/USB come empty

What we tried:

  • In the 3D_people_track_6843_dss -->  processInst->aoaInput->clutterRemovalFlag = 0
  • .cfg --> staticRangeAngleCfg -1 1 8 8

 

After tried to modify the dps firmware disabling the clutterRemovalFlag and enabling the staticProcEnabled, we stil not having the cloud points when people stop to move.

We need the cloud points even when someone is not moving.

Best.

  • Hello,

    You should enable the FineMotion chain which allows the detection of stationary people. For example, please try the AOP_6m_staticRetention.cfg chirp configuration which has fineMotion enabled. I would also change this to

    fineMotionCfg -1 1 1.0 1 5
    To allow for stationary targets to appear every frame.
