Abstract

Coherent jamming to SAR(Synthetic Aperture Radar)is hard to put into practice because of big amount of computation.This thesis has analyzed SAR coherent jamming theory

2-D convolution algorithm for SAR coherent jamming signal generation

and provided a fast algorithm.The computation procedures of these tow algorithms were analyzed in detail

and the simulation was also processed.Both theoretical analyses and simulation results indicated that fast algorithm could reduce complexity and computation amount of azimuth-processing greatly for SAR coherent jamming signal generation.Combining with modern fast digital signal processing technology

this fast algorithm could be used to generate SAR coherent jamming signals sequentially in real-time.
