AWR1642BOOST: CFAR to show top N objects instead of all objects over set dB threshold

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: MMWAVE-SDK

Hello, our development team would like to know is there a way to find the top N magnitude objects from CFAR instead of all the objects over the set CFAR range threshold.

So far, we are using MATLAB to find the xyz coordinates, rangeIDX, dopplerIDX, and peakValue of detected objects over 15dB. We would like to know which objects are the strongest reflection.

Right now, sometimes with 15dB and objects moving we detect no object/ one object/ many objects.

Thank you!

    Hi Michael,
    Based on mmw demo of mmwave-sdk, if you go over the document (mmw\docs\doxygen\html\index.html) to find out the processing chain flow where during the FFT processing DSS does the CFAR detection. So just before that step you can find out all the detected objects which are not yet chunked off through CFAR threshold.
    Please follow the document and source file (dss_data_path.c: mmwavelib_cfarCadB_SOGO).

    Regards,
    Jitendra
