AWR1843: AWR1843: Running Radar Processing Chain (Range/Doppler/CFAR/AoA) using R4F + HWA

Part Number: AWR1843

Hi team, 

I found an out of the box demo for xWR64xx which run entire radar processing chain (Range/Doppler/CFAR/AoA) using R4F and HWA, no DSP. I may want to make use of this demo and migrate to XWR1843. Then add dbscan clustering + gTrack into DSP. I am not sure if anyone has tried this approach. Can you please share if any bottle necks or any potential issues. 

Thanks, 

QL

    Hi QL,

    We already have a demo for a similar use case. Please refer to the following application available on TI resource explorer. 

    Medium Range Radar

    Hi Kaushik, 

    Thanks a lot for your input. I have walked through this demo; however, it does not fit 100% to our needs, but it is definitely a good reference source. From my understanding, range/doppler processing run on HWA (controlled by DSP), but CFAR and elevation/azimuth estimation still on DSP. 

    As I may need to add some more advanced algorithms on DSP, so I'd like to free up DSP resources. My idea is to migrate CFAR and Elevation/Azimuth estimation to HWA and controlled by ARM core (not by DSP core). Do you foresee any risks or disadvantages? 

    Thanks, 

    QL

    Hi QL, 

    I cannot think of any risks at the moment. You should be able to achieve your use case as you mentioned. One suggestion would be to avoid manual triggering of the HWA from ARM as much as possible to save on time. (Eg: Try using ADC sharing with HWAMEM, chaining FFT's and CFAR etc).

    Regards,
