AWRL6432: Detmatrix has all doppler spread in 5.3L SDK.

Hi Clinton,

We captured this det-matrix and radar-cube inside lab. In the scene, only adult is standing still at the boresight of radar. We are sure that there are no any static or moving objects in the scene. Since, there is only one adult and he is still, there should be peak around dopplerbin 0 and there should not be any peaks in that respective range column as there are no movments. But there is a all-doppler-spread in that respective range column.

Why is that so?

Please let me know, if you have any questions

Hi Girish,

Do you have windowing enabled for the Doppler DPU? If so, could you provide which window you are applying?

Thanks,

Clinton

Hi Clinton,

We are using the default mmw_demo Doppler DPU windowing which is hanning.

Hi Clinton,

Sorry by mistake I closed the threade, Please let me know if you want to open a new related thread.

Hi Girish,

No worries, it's open again, we can continue discussing here.

Could you provide the radar cube data and MATLAB script you're running for us to analyze?

I also wanted to ask about checking this against other hardware - have you replicated this same behavior on another 6432 EVM? It would also be interesting to see the results of the same test with the 6443 EVM. Could you run that experiment?

Thanks,

Clinton

AlldopplerSpreadIssue.zipHi Clinton,

Checked with another hardware, still we are seeing the issue. We did not have 6443 EVM. We attached binary and matlab script here

Hi Girish,

Thanks for sending this over. Please allow some time for me to evaluate.

Noting that issues here were resolved mostly through updates to config parameters.
