AWR1243: Porting mmWave sdk code to RADAR SDK

Part Number: AWR1243

Hi ,

We are trying to integrate the Gesture-Swipe code present in mmWave Industrial toolbox for IWR-14xx into RADAR SDK for AWR1243. Is it possible to do so? . So, we are not sure of porting of " mmWave arch code of IWR14xx" into Radar SDK using AWR12xx is possible?

Kindly help us to clear our thoughts.

Regards,

Varsha 

 

  • While porting with Radar SDK for AWR1243 you need to implement same FFT processing, feature extraction and gesture classification on TDA3x device.
    FFT processing reference should already be there in Radar-SDK so next you need to take other gesture recogition process to TDAxx.

    Hi Jitendra,
    Thanks for the reply!

    While going through the Gesture code we came across some of the library functions. Can you help us understand them by giving a brief idea, have doubts in follwoing functions:
    1. MmwDemo_dcRangeSignatureCompensation and is Clutter removal important to perform while porting in RADAR?
    2. Gesture_findNumDetections function, one of the input parameter of this method is "rangeDopplerLogMagMatrix" , how to get this in RADAR sdk?
    3. MmwDemo_configAngleEstimation_HWA present in "Gesture_angleEst" func.

    Thanks in advance!!!

    Hello Varsha,

    1. MmwDemo_dcRangeSignatureCompensation and Clutter removal are optional, without enabling these feature also Device should able to detect Gesture.
    2. rangeDopplerLogMagMatrix is copied as output of HWA, where eDMA transfer 2D ABS from accelerator output to L3 memory (rangeDopplerLogMagMatrix). You can refer AWR16xx mmw where equivalent parameter is 'detMatrix'.
    3. This function is equivalent to Azimuth calculation of mmw demo (dss\dss_data_path.c).

    Many of DSP library function used in the application you need to find equivalent of same in Radar-SDK.

    Hi Jitendra,
    Thanks a lot for the reply.
    As per your previous reply : "FFT processing reference should already be there in Radar-SDK so next you need to take other gesture recogition process to TDAxx."

    So the output of FFT's of :
    1) IWR 1443 Gesture recognition Swipe & 2) The FFT present in Radar SDK are exactly same ?
    Is there any need to use the FF T of Gesture here?

    Hi Varsha,
    In IWR1443 it might be using Hardawre accelerator to do the FFT. For the gesture you need to extract the feature out of raw data. And for that basic 1-D and 2-D FFT will be same as it should have done on TDAxx side as well. Post 2-D IWR1443 will be doing the feature extraction which you need to port on TDAxx.
