AWR1843BOOST: How to use the HWA for USRR in lab11 "MRR beamsteering"?

Morris Huang

Part Number: AWR1843BOOST

Hi,

According to these website, I know the USRR mode in lab11  "MRR beamsteering" is not involved by HWA.

https://e2e.ti.com/support/sensors/f/1023/p/922595/3410351

https://e2e.ti.com/support/sensors/f/1023/t/943868

Now, I want to let  HWA involve the MRR/USRR mode simultaneously in lab11 "MRR beamsteering".

Please help us to achieve it.

Thanks.

Morris

    Hello Morris,

    Our software team will review your concern and respond tomorrow.

    Thankyou for your cooperation.

    Hi,

    What is the reason you want to use the HWA?

    if you need to use the beam steering cabability, it will be much easier to port the beamsteering capabilitites to the MRR demo that does not use the HWA, lab0007.

    It is possible to debug the lab11 and fix the bugs for the USRR sub frame, however that will probably take much longer

    thank you

    Hi, Cesar

    In fact, we have already ported the  beamsteering capabilities to our project without HWA.

    But the processing time is not ideal.

    Then we want to use HWA to improve the processing time.

    Thank you.

    Thank you,

    I understand what you are trying to do.

    When the code with HWA was developed we did not have sufficient time to validate the USRR subframe.

    Here are the steps that our team would take if we had the time to further debug this code.

    1) configure the demo in USRR only mode - it will be easier to debug if the demo runs only USRR frames.

    TEST THE RANGE FFT

    1) Place a strong reflector in front of the sensor.

    2) Run the demo and place a breakpoint in the code after the 1D FFT is completed.

    3) Save one chirp using CCS to a bin file.

    4) Open and display the bin file using Python or Matlab. Make sure there is a peak present at the expected range.

    TEST THE DOPPLER FFT - CREATE A TEST VECTOR

    1) Mount the Radar sensor on a moving object such as car

    2) While the car is moving, set a breakpoint after 1D FFT processing.

    3) Save the radar cube (the output of 1D FFT for all chirps) to a bin file using CCS

    TEST THE DOPPLER FFT

    1) Run the Demo, set a breakpoint after 1D FFT processing complete

    2) Load using CCS the test vector created above

    3) Execute the 2D FFT

    4) Compare to Matlab

    There are also other ways to debug this. It depends on the experience with the demo

    thank you

    Cesar
