Abstract :
A echo simulation algorithm for natural scene is presented. It is based on the model of equivalent scatterer for the scene, the approximate expression of SAR system transfer function, and one-dimensional fast Fourier transform (FFT) for data processing. The validity and correctness of the algorithm are verified through raw echo data simulation of point target and natural scene.
