In ground-based frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) images, false targets caused by coupling signal may appear. Traditional digital cancellation methods cannot estimate reference cancellation signal in real-time. A new method based on singular value decomposition (SVD) to suppress radar coupling signal is put forward. In slow time coupling signal is changeless...
FMCW radar with deramping technique has many advantages comparing to traditional pulse radar. But the expressing of signal error becomes more complicated. The distortions on amplitude and phase are unavoidable for wide bandwidth and wide pulse signal, which have a serious impact on the imaging quality. Aiming at the problem of signal error correction, the echo signal model of FMCW radar with amplitude-phase...
