AWR2243: Running the real-time processing programs on the 4-cascade AWR2243+MMWCAS-DSP-EVM platforms, I found TXBF mode lacked CFAR, DOA and other algorithms

Part Number: AWR2243
Other Parts Discussed in Thread: MMWCAS-DSP-EVM,

Hi Team,

I used RADAR_SDK to run a real-time processing program on the 4-cascade AWR2243+MMWCAS-DSP-EVM platform and found that the Doppler diagram and point cloud diagram were missing in TXBF mode. I compared the MIMO and TXBF programs and found that the MIMO program had CFAR, DOA, etc., while TXBF mode didn't have. Where could I find the CFAR and DOA algorithms of TXBF, or does TXBF not have these?

If these algorithms of TXBF don't exist in the SDK, can these algorithms of MIMO be transplanted to TXBF mode?

Kind regards,

Katherine

    The original post was supported by Christ Meng, but the customer requested that his question be posted onto the E2E support forum for help.

    Christ replied that CFAR should be similar while DOA was different. He suggested that the customer should check "mmwave_studio_03_00_00_14\mmWaveStudio\MatlabExamples\4chip_cascade_TxBF_example" and implement it by himself.

    The customer replied that there were 2DFFT  CFAR  AOA and yet no DOA (as show in the picture below). He would like to know whether AOA was different as well or not.

    Christ replied that the DOA he mentioned was calculating the angle and that the TX BF function in the sdk had not been verified. So Christ suggested the customer refer to the matlab example to implement it.

    The customer replied that he had tried adding algorithms such as CFAR to TXBF mode in the SDK, but he still had no clue.

    Hi,

    For TXBF, only proof of concept of beam stitching is available in the SDK. You need to implement your own complete chain including detection. The algorithm itself in MIMO applies to TXBF, but it is not plug and play. You need to understand the input/output and the algorithm itself for tune.
