Abstract :
In this paper, a modified two-step RCMC method is proposed for SA-FBSAR. Comparing with the traditional two-step method, the sequence of the two-dimensional RCMC operations is altered to accommodate the significant nonlinearity of RCM in SA-FBSAR, and the influence of such modification on imaging process is taken into account. Simulation results with point scatterers demonstrate the validity of the proposed RCMC method.
