FMCW Radar - Chirps


Has anyone been able to produce frequency chirps using the LimeSDR (with preference for gnuradio solution)? I am trying to do a FMCW radar due to the need of reading RFID tags through backscattering. The problem here is, I don’t have any circulator, so i thought maybe with an FMCW radar and a band pass filter I could somehow eliminate the crosstalk that exists from Tx to Rx.

Thanks in advance

Already been able to do it, but can’t manage to have a bandwith greater than 75 Mhz. Any solution? Thanks
