    Hello,
    I found that the RF data consists of 1536 range bins but the baseband data consists of 188 range bins. Does some distance information loss during the downconversion?

    Thanks

    Hi Wangyc,
    There is no lost of information after downconversion. The downconversion will shift high frequencies to low frequencies around the DC component of the signal. The baseband data consists of 188 bins due to the decimation factor 8 after downconversion and filtering processes.

    Best regards,
    Chouaibou.
