  • There is a growing interest in the Frequency Modulated Continuous Wave (FM-CW) SAR for its small cubage, light weight, cost-effective and high resolution. In this paper, the principle of the de-chirped FM-CW SAR is analyzed in detail, the phenomena, for example, Residual Visual Phase (RVP), Slope, range walk are discussed deeply, and the improved range Doppler imaging algorithm for the de-chirped FM-CW SAR is presented. The deduction and the simulation prove the algorithm is feasible and correct.
