AWR1843: how to access the range profile, noise profile and heapmap when using Object Detection with only rangeProcHWA DPU

Part Number: AWR1843

Hi

When I using" Object Detection with only rangeProcHWA DPU mode" in AWR1843, I find the detMatrix, radarCube and azimuthStaticHeatMap in the ptrResult structure are all 0, so I can not get the range profile, noise profile, and heatmap that can be access when using "Object Detection using DSP mode". Is there any method that I can get these data?

Thanks

    Hi,

        Please give me some time. Let me go through this in the code and get back to later next week by Friday.

    Thanks and Regards,

    Akshay.

    Hi,

        Thanks for your patience. I did go through the entire file of: objdetrangehwa.c in C:\ti\mmwave_sdk_03_05_00_04\packages\ti\datapath\dpc\objectdetection\objdetrangehwa\src which uses "Object Detection DPC implementation with range HWA DPU only". However, it is seen that this file only calculates range-FFT using "DPU_RangeProcHWA_process" function. So after the execution of this file you would not have range-profile, noise-profile and detection matrix ready.

       In case you want to use HWA , you could use the file objectdetecion.c in the folder C:\ti\mmwave_sdk_03_05_00_04\packages\ti\datapath\dpc\objectdetection\objdethwa\src where the process of range-FFT, Doppler FFT and Angle FFT  with CFAR are calculated and you would get all that you wanted like noise-profile,  range profile and heatmap.

     Please let me know if you have any questions after going through the above suggestions.

    Thanks and Regards,

    Akshay.
