摘　　要：首先介绍了SAR时域压缩距离成像算法,同时研究了匹配滤波成像算法。经分析表明,由于与信号目标回波进行匹配的信号中不仅包含了相位信息,还包含有幅度信息,所以匹配滤波成像的效果非常理想,并且对噪声干扰也有很好的滤除作用。最后利用模拟试验的方法验证了这一结论。This paper introduces firstly the algorithm for Synthetic Aperture Radar （SAR） range imaging in time-domain compression. Basing on this, the authors study the algorithm of matched filtering imaging analysis. Result shows that the algorithm to matched filtering imaging is very good by analyzed, because the signal matched to the echo of targets includes not only phase but amplitude information. At the same time, the algorithm can also filter out noise jamming. At last the authors validate the conclusion by use of computer simulation.
