CCS/IWR1642BOOST: Increasing people detection range in lab0011-pplcount (above 14m)

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Tool/software: Code Composer Studio

Hi,

Is there any way to Increasing people detection range in lab0011-pplcount over 14m, I tried to change the cfg file but nothing gave good results.

Attached my cfg thats works for 14m:

'dfeDataOutputMode 1',
'channelCfg 15 3 0',
'adcCfg 2 1',
'adcbufCfg 0 1 1 1 ',
'profileCfg 0 77 30 7 62 0 0 24 1 128 2500 0 0 30',
'chirpCfg 0 0 0 0 0 0 0 1',
'chirpCfg 1 1 0 0 0 0 0 2',
'frameCfg 0 1 128 0 50 1 0',
'lowPower 0 1',
'guiMonitor 1 1 0 0',
'cfarCfg 6 4 4 0 0 16 16 4 4 50 62 0',
'doaCfg 600 1875 30 1',
'SceneryParam -12 12 0.05 16',
'GatingParam 4 3 2 0',
'StateParam 5 5 10 100 5',
'AllocationParam 100 0.01 8 1 2',
'VariationParam 0.289 0.289 1.0',
'trackingCfg 1 2 250 20 200 50 90',
'sensorStart'.


What should I change in order for it to detect up to 40m?

  • Hi Oren,

    1. The profile config "profileCfg" controls the physical characteristics of the chirp.  This will have to be changed to increase the range. See this document and the sensing estimator for help.  The cli command is described in the SDK user's guide.
    2. The Scenery Params control the valid tracking Area.
      1. 'SceneryParam' <-X, Left edge> <+X, right edge> <Y, close boundary> <Y far boundary>
      2. These need to be modified to allow tracking in the area of interest.

    For distances over 20 meters, I recommend following the directions on this page to use the 50m chirp for IWR1642.  Please read all instructions to ensure you use the right demo software.

    Regards,
