Part Number: AWR1642
I'm trying to implement people count demo on AWR1642BOOST-ODS. I made following modification on chirp config :
"SceneryParam 0 3 0.05 4" I put the board on the corner of my room
"AllocationParam 10 0.01 15 1 2" due to lower antenna gain on AWR1642BOOST-ODS I decreased minimum total SNR to 10 and minimum number of points to 15
Then I ran the demo , it gave me a rich point cloud on visualizer when I walked in front of it but it didn't assign any track. Please tell me how to configure chirp configuration to make it work on AWR1642BOOST-ODS.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

The People Counting lab is developed for a radar system that has a virtual antenna pattern of 8 Virutal Rx in a row. The Signal chain works as follows:
1D Range FFT - 2D Capon Beamforming for Range/Angle Heatmap - CFAR on Range Angle/Heatmap - Doppler FFT for velocity of each detected point
As you can see, both Angle of Arrival (AoA) and Detection in this chain rely on having the assumed Virtual Rx pattern. When running this demo on 1642ODS, you have a different Virtual Rx pattern - as a result, the heatmap and detected points are incorrect. You will still have detections, but these will not correlate welll with real world locations of objects, resulting in the tracker failing.
To make the demo work in 3D, you will need to do the following:
For step 1, you can use the OOB demo for the ODS.
For step 2, please see:
For step 3, please:
