    Sample per frame is 512, so there are 512 data in each frame.
    Chirp per frame is 4
    Sample per chirp is 64
    What does there 512 values stand for?

    Hello,

    Sorry for the delay in our response.

    Data format for different options to record data from "Radar GUI" is mentioned in the "Recording and Playback" section of the help document. I understand that, you are already went through this document.
    Please give us some time to check, why "Samples_per_frame" is mentioned as 512 in log messages instead of 256 (Chirps_per_frame * Samples_per_chirp) in the log messages internally with our product experts and get back to you.

    Thanks and Regards,
    Sudheesh

    Hello,

    We discussed your query internally with our product experts. The reason why you observe the "Samples_per_frame" filed equal to 512 instead of 256 (4 * 64) is that, each sample contain real (I) and imaginary (Q) parts.
    Please see the field "Data_Format_Enum", its value is '1'. Which means each sample will be recorded as a complex number. First 64 samples will come from I channel and next 64 samples will be from Q channel.

    Thanks and Regards,
    Sudheesh
