IWR1843BOOST: How is the data arranged in the .bin file of echo data collected by the IWR1843BOOST and DCA1000?

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: IWR1843, IWR6843, AWR1642, AWR1843

How is the data arranged in the .bin file of echo data collected by the IWR1843BOOST and DCA1000? I have looked up some documentation such as "Mmwave Radar Device ADC Raw Data Capture" and "mmwave_studio_user_guide", but none of them explain the data arrangement of the echo data collected by the IWR1843BOOST and DCA1000.

    Alternatively, is there a MATLAB example available for processing the .bin data collected by the IWR1843 + DCA1000? I came across a MATLAB data processing example for the AWR1843 + DCA1000 in another post—does this apply identically to the IWR1843 + DCA1000? Additionally, can the IWR1843 + DCA1000 refer to the data arrangement and MATLAB processing examples of the AWR1642/IWR6843 + DCA1000 for reference?

    Hello,
    We have received your post and the investigation will take some time.
    Thanks for your patience.

    ADC data is in non-interleaved format. 

    Path to the document: "C:\ti\mmwave_studio_02_01_01_00\docs\mmwave_studio_user_guide.pdf".

    You can find the MATLAB script in mmWave Studio folder - "C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\MatlabExamples\singlechip_raw_data_reader_example\rawDataReader.m".

    Yes, you can use the same script for AWR1843 and IWR1843.

    Yes, you can.
