MMWCAS-RF-EVM: Post-Processing data in Matlab to get azimuth heat map and 3d point cloud

Part Number: MMWCAS-RF-EVM

I have trouble with the matlab postprocessing of the data that's collected using the lua scripts. I keep getting an error "Unknown parameter file or too many chirpProfiles_*.json file!!" when I try to run the cascade_MIMO_signalProcessing.m file using the default calibration values (calibration_dummy or calibration_high mat files). I have setup the folder/path and file names in the testlist correctly.

I'm attaching a picture of the error that I am getting in Matlab. When I do check the location where the collected data is stored there is only one *.mmwave.json file, so I'd like to know how to fix this error.

Thank you,

    Hello Lakshmi,

    Thankyou for reaching out.

    I see you've captured data using mmWave Studio 03_00_00_14, but in the testlist.txt file, the capture directory is pointed towards mmWave Studio 02_01_00_00.

    Can you correct this mismatch and try again?

    Please let us know your observations.

    Regards,

    Ishita
