AWR1843BOOST: Getting Y axis as 0 in certain frames

Part Number: AWR1843BOOST

Tool/software:

Hai,

In AWR1843BOOST when flashed MRR demo with USRR 30 m cfg and by enabling LOW_THRESHOLD_FOR_USRR i am getting Y axis reading as 0 in few frames.

is this because of noise?. If YES how can we avoid it....like by implementing an low pass filter.

Thanks & Regards,

Rehman

    Hi Rehman,

    In MRR demo, static clutter is removed. So, I don't think it's the clutter. But if you are enabling LOW_THRESHOLD_FOR_USRR, you are eventually enabling the detection of weaker targets. Can you disable LOW_THRESHOLD_FOR_USRR and check the behaviour? Any particular reason for enabling this macro?

    Can you confirm if Z-coordinate is 0 or Y-coordinate is 0?

    Regards,

    Hai,

    Actually we need to detect plants and trees.........so that's why we used this macro.

    so is there anyway to avoid this Y = 0m detection...only Y coordinate is 0.

    Thanks and Regards,

    Hi Rehman,

    Enabling LOW_THRESHOLD_FOR_USRR might not be tested. I see that obj->peakValThresholds[0].threshold is larger than the threshold when the macro is disabled in MmwDemo_populateUSRR. Based on your experiments, you need to fine tune the thresholds.

    You can update the thresholds in dss_main.c based on your analysis.
