Abstract :
A novel algorithm for SAR(Synthetic Aperture Radar) raw signal simulation based on sub-aperture processing is proposed. The fundamental of the algorithm is analyzed, the signal model is deduced, as well as the simulation procedures are given. Simulation results of extended scene have shown that in the condition of meeting simulation precision, the simulation speed of the algorithm is higher than that of the echo simulation algorithm based on 1D FFT(Fast Fourier Transform).
