IWR6843: Long Range People Count: Configuration Documentation Discrepancy

Part Number: IWR6843

Hello,

I've been working on calibrating the Long Range People Counting demo and have noticed some of the parameters in the default configuration do not match the SDK or Demo Documentation. The following parameters I cannot find an absolute match for.

  • cfarCfg
  • doaCfg
  • AccelerationParam
  • trackingCfg

When trying to get a less noisy and reduced ghosts are there any recommendations on how I use these parameters if applicable? Thanks!

    Hello Zach,

    I've attached the chirpParams CLI command details for cfar and doa

    The trackingCfg is 3884.chirpParams.xlsx

    AccelerationParam <max_accel_X> <max_accel_X> <max_accel_X>

    Maximum targets acceleration in lateral, longitudinal, and vertical directions correspondingly. Used to compute processing noise matrix. Units m/s2

    trackingCfg <enable> <paramSet> <numPoints> <numTracks> <maxDoppler> <framePeriod> <azimuthTilt>

    These parameters are generally not used - please refer to the ppl count customization guide which provides hints for removing ghosts. Please also note that this is example demo code and note production code. The development of additional algorithms or features for handling and reducing ghosts for your application may be required if tuning as suggested in the document is not sufficient.
