摘　　要：针对相邻脉冲包络相关法在对齐回波脉冲时存在漂移误差和突跳误差的问题,提出了一种以滑窗平均距离像作为基准脉冲的包络相关对齐方法.该方法较好地解决了漂移误差和突跳误差的问题,具有较小的计算量.理论分析和实际数据的处理结果表明了该方法的有效性.Aimed at the problems of drift errors and jump errors using correlation of the envelope alignment between the neighbor pulses, a method of echo envelope alignment correlation was proposed, based on average range profile of pulses in the sliding-window as a reference pulse envelope. The approach well solves the problems of drift errors and jump errors with little computation. The theoretical analysis and the results of processing real data show that the method is valid.
