AWR2243: DDMA band question on mmWave SDK 4.3 test log

Part Number: AWR2243


Hi team,

Can you please provide the chirp configuration to generate this test log file in SDK4.3?  "C:\ti\mmwave_mcuplus_sdk_04_03_00_01\mmwave_mcuplus_sdk_04_03_00_01\docs\testlogs\am273x\LVDS_capture\ddm\postProc.jpg"

And, can you please explain is this DDM doppler plot should have 4 band or 5 band? Which code or tools is use to generate this postProc.jpg by RAW_0.BIN and LogFile.csv at same folder.

Thanks.

Thanks.

Regards,

Wesley

    Hi Wesley,

    Please look into the C:\ti\mmwave_mcuplus_sdk_04_03_00_01\mmwave_mcuplus_sdk_04_03_00_01\ti\utils\test\cbuff_stream which has the configuration you are looking for.

    The post processing is from a custom Matlab script which is not shared publicly I believe. Recommended to use the post processing provided by mmwave Studio. In this case the doppler plot has 4 sub bands. We usually go for 2^N or 3x2^N point FFTs as a result of which we have either 6 or 3 sub bands (not 5).
