| Abstract: The spurious-free dynamic range of a wideband radar system is increased
by apportioning de-ramp processing across analog and digital processing
domains. A chirp rate offset is applied between the received waveform and
the reference waveform that is used for downconversion to the
intermediate frequency (IF) range. The chirp rate offset results in a
residual chirp in the IF signal prior to digitization. After
digitization, the residual IF chirp is removed with digital signal
processing. |
