摘要
随机跳频脉冲信号的运动补偿是雷达信号处理中的难点 ,本文采用伪随机的方式 ,即在各脉组间采用同一随机编码序列 ,来产生随机跳频脉冲信号 ,从而大大简化了信号的复杂度 ,并在此基础上设计了一种简单可行的运动补偿方法%D%D前后正负跳频脉组比较法。分析表明 ,采用伪随机的方式对原始信号的分辨性能没有太大的影响。所提出的方法具有运算量少 。
The motion compensation for the hopped-frequency pulses is a difficult question in the field of the processing of Radar signals, this paper adopts the form of pseudorandom, that is to adopt the same random coded-sequence in different pulse lists, to produce the hopped-frequency pulses . And based on it the paper advances a simple and feasible method for the motion compensation by comparing the two consecutive pulse-sequences positive and negative in order. The analysis indicates that the introduction of the pseudorandom doesn't much influence the distinguish power of the original signal. And the method advanced for motion compensation has the merits of less computational complexity and real-time- processing.
