AWR1843BOOST: CFAR Proc test data code

Part Number: AWR1843BOOST

Hi everyone,

              I ran the unit test code for CFAR Proc which used a test data. The main file of the CFAR Proc says that the test data is generated using MATLAB but I can't find MATLAB Code. Where do I find it to better understand CFAR?

    Hi,

    Can you please give us the path to the file that you used?

    We have to check with developer how the code was generated.

    thank you

    Hi,

          The path to the file : C:\ti\mmwave_sdk_03_03_00_03\packages\ti\datapath\dpc\dpu\cfarcaproc\test

    Sincerely,

    Anushka

    Anushka,

    You can better understand the CFAR processing by looking through the Doxygen included in the mmWave SDK that specifically discusses the CFAR DPU.

    You can find this Doxygen file at this location: C:/ti/mmwave_sdk_03_04_00_03/packages/ti/datapath/dpc/dpu/cfarcaproc/docs/doxygen/html/index.html

    This is the location in the latest SDK release.

    Regards,
    Kyle

    Hi Cesar,

              Thank you for reverting back. I just wanted to know how cfar_test_data.bin in C:\ti\mmwave_sdk_03_03_00_03\packages\ti\datapath\dpc\dpu\cfarcaproc\test\testdata is generated in MATLAB?

    Sincerely,

    Anushka

    The cfar_test_data.bin file is generated as part of the SDK. It is a set of unsigned 16-bit values that are reconfigured through a variety of range and doppler bin combinations. The data is then sent through the CFAR DPU and the results are displayed in CCS.

    The definitions TEST_DOPPLER_BIN_SIZE and TEST_RANGE_BIN_SIZE along with a few others are configurable so they can be changed as desired. Please refer to the comments on these definitions to understand the upper and lower bounds on these values.

    This data simulates a saved detection matrix. You can learn more about the detection matrix by looking at the Doppler DPU found in this file location:

    C:\ti\mmwave_sdk_03_03_00_03\packages\ti\datapath\dpc\dpu\dopplerproc
