摘　　要：步进频合成宽带处理可以在较低的瞬时宽带条件下合成更高的带宽,实现高的距离分辨力。步进频合成宽带的工程应用中仍然存在着地杂波影响下的速度补偿等实际问题。论文阐述了步进频合成宽带的基本原理,仿真分析了杂波对步进频合成宽带的影响并进行了对比分析,最后给出了工程应用的一些有益结论。Stepped-frequency synthetic wideband process can achieve high range resolution by synthesizing multiple pulses based on narrow-band pulse.In engineering application of the method,realistic questions are also existed such as velocity compensation influenced by ground clutter.In the paper,the principle of stepped-frequency synthetic wideband process is introduced,and the clutter influence is simulated and analyzed by comparing.Finally,the conclusions which are useful for engineering application are given.
