摘　　要：首先介绍基于合成距离包络,时域合成和频域合成技术的三种合成距离高分辨线性调频步进信号的方法。在此基础上,对这三种方法在运算量和性能上进行比较,并分析了运动对它们的影响。最后分析了它们在SAR/ISAR中的运用。仿真结果证明了本文分析的正确性。Introduction to three synthesis methods of high resolution linear FM stepped-frequency signal by applying synthetic range profile （SRP）, time-domain synthesis and frequency-domain synthesis techniques is given. Computation burden and performance comparison between these three methods are made, movement effect to each method is analyzed and their application in SAR/ISAR field are described. Correctness of the analysis made in the paper is verified by simulations results.
