IWR1443BOOST: How to customize the lab0016_zone_occ_14xx by configing file :mmw_zone_occ_demo_14xx.cfg

IWR1443BOOST:

UTS song1
Prodigy 40 points
Part Number: IWR1443BOOST

Hello there, 

I'm using your Iwr1443borad. I would like to get more point of the point cloud, the config now can only get 64 points in one frame from the demo "lab0016_zone_occ_14xx". Could you tell me how to change the ".cfg" file to get more points?

Regards,

Xudong

    Hello Xudong,

    The limitation in the OOB SDK demo is due to memory and UART data transfer time. In CFAR the search proceeds across the range,doppler fft detection matrix search until the max number of supported pts are detected. Higher range-doppler indices may not have detections reported if your CFAR threshold is set so low that you hit the max.

    If you are already hitting the maximum then you would need to modify the demo source code to better optimize the memory and data transfer time. If you are not hitting the max then you can adjust the thresholds in the cfarcfg command to change the sensitivity and enable more points to be detected.
