There is a growing interest in the frequency modulated continuous wave (FMCW) SAR for its advantages such as small cubage, light weight, cost-effective and high resolution etc. In this paper, the de-chirped FMCW SAR signal’s imaging process is analyzed in detail, the method of range migration correction is studied, and the improved imaging algorithm is presented. The derivation and the simulation proved the improved algorithm is correct and feasible.
