CCS/IWR1843BOOST: The Gating value selection of the Gtrack algorithm in the traffic monitoring demo

Rata Zhang
Expert 2840 points
Part Number: IWR1843BOOST

Tool/software: Code Composer Studio

Hi,

   In the demo for the 2D condition, the gain value is set as 20 as  below:

    gatingParam 20 15 15 15 200

and the patamter G  is equal to this value,

    inst->G = inst->gatingParams->gain;

The the gating value G is called as belows:

 

In the document "Tracking radar targets with multiple reflection points ", the description is

I understand that the volume is constant, and the G is changed as the the group residual covariance matrix CG. But  in  the demo, The G is constant, is that right?

 

Regards,

Rata

    Hello,

    Which lab are you referring to? There are slighlty different versions of the tracker with different behavior for Gain.

    Hi Amanda,

      My reference SDK is mmwave_industrial_toolbox_4_3_2, in the path C:\ti\mmwave_industrial_toolbox_4_3_2\labs\traffic_monitoring\18xx_68xx_traffic_monitoring\chirp_configs\18xx_traffic_monitoring_70m_MIMO_2D.cfg.

    Hello Rata,

    The document is not up to date with the latest version of the gtrack. The gain value is a constant multiplier that multiplies object dimensions to create the gating function.
