AWR1642BOOST: About threshold for angle FFT result

Part Number: AWR1642BOOST

Hello.

I want to ask the question about threshold for angle FFT result.

Please see the picture below. This picture is my experiment result.  I put two stationary targets in same range (about 1.4 meter) and confirmed the result by mmwave demo visualizer ver 3.1.0.

This result looks good because both targets can be detected. In this result, radar detected two targets from one range bin, so I think there is the threshold for angle FFT result.

What kind of threshold is this? And can I control this threshold by changing parameter?

Regards,

Nobu

    Hi,
    In the CLI command 'multiObjBeamForming' uses threshold scale for the second peak detection in azimuth FF output. This may impact your result.
    Please refer mmwav_sdk_user_guide.pdf for 'multiObjBeamForming' details.
