Abstract:
The combination of frequency modulated continuous wave (FMCW) and SAR (synthetic aperture radar) , is one of the most important and dynamic research around the world. For FMCW SAR, traditional approximation of stop-go is invalid, hence the traditional motion compensation method is no longer suitable for FMCW SAR. The signal model of FMCW SAR in the presence of motion error is derived in the paper, as well as the difference introduced by inter-pulse motion errors. Then a new motion compensation method is proposed. Simulated and experimental FMCW SAR data is generated and the well-focused image shows the proposed method is available.
