AWRL1432BOOST: Can NOT set the SNR threshold in the mmwave_demo

Part Number: AWRL1432BOOST


Tool/software:

Dear awr1432 expers,

I play and study the \MMWAVE_L_SDK_05_05_00_02\examples\mmw_demo\mmwave_demo and found out I can NOT set the SNR threshold to filter the weak object detection.

I try to set the SNR threshold use cfarCfg and cfarScndPassCfg commands in the profile as follows.

cfarCfg 2 4 3 2 0 12 1 0.5 0 1 0 0
cfarScndPassCfg 1 2 8 4 3 1 12 1

As the above, the Range CFAR and Doppler CFAR should filter out all detections SNR lower 12 dB.

However, that seems does not work at all.

Do I mis-understand the meaning of the parameters of cfarCfg and cfarScndPassCfg?

Help please.
