@Envidia - There are techniques to "synthesize" an LFM pulse with a wide bandwidth (say 2 GHz) out of 10 200 MHz LFM pulses, and then successfully process the 10 pulses as if they were one long 2 GHz pulse. Go back and read my comment from Nov 21.
@SteveSh Of course, but given his questions it didn't seem to me that he was doing one of the stepped FM/LFM techniques, but having more fundamental issues on how to dechirp which seems to be the case, barring any further updates from OP.
