摘要
对合成孔径雷达(SAR)相干干扰由于计算量大而难以实施.本文在分析SAR相干干扰原理、用于SAR相干干扰信号产生的二维卷积算法的基础上,提出了一种快速算法.对两种算法的运算过程做了详细分析,并进行了仿真计算.理论分析和仿真结果表明,该快速算法大大简化了SAR相干干扰信号产生的方位处理过程,减小了方位处理计算量.结合现代高速信号处理技术,该快速算法可用于SAR相干干扰信号的连续、实时产生.
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 modem fast digital signal processing technology,this fast algorithm could be used to generate SAR coherent jamming signals sequentially in real-time.
