Abstract

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 author deduced the imaging process in detail, discussed the production and the removing of residual video phase (RVP) as well as the slope factor, then the improved imaging algorithm is presented by combination de-sloping, range migration correction with pulse compression. The derivation and the simulation proved the algorithm is feasible and correct
