    Hello Rata,

    The profile configuration provides the FMCW  course values of the chirp properties , whereas the chrirp configuration provides the chirp to chirp variations on top of the chirp profiles. Parameters in the chirp configuration  provide the dithers used in the configuration which is additionally to the programmed configuration in the profile config.

    I would suggest you to refer to the Radar Interface control document in the MMWAVE-DFP for the details of the profile configuration and the chirp configuration.

    Thanks,

    Raghu
