    Hi,

    I am trying to understand the basics of X2M200 module. From the radar data I get 52 Bins each 0.037 m length, with Fs ~ 4e+10. But if use the formula c/Fs/2 the bin length I get is 0.0037 which is exactly 10 times smaller. Is there any mistake I am doing in this calculation?

    Thanks a lot

    Hi Mo,

    I suspect the bins you get is baseband data, which is downconverted from RF data with some decimation factor.
