| 摘 要： | 调频步进信号指的是采用线性调频信号取代简单脉冲,作为步进频信号子脉冲的信号形式。采用基于相参频谱合成技术的步进频信号处理方法,解决传统步进频信号处理方法距离模糊严重、易于产生伪峰的问题。理论分析和仿真结果表明,只要参数设计合理,该方法能够有效实现步进频信号的子脉冲合成,得到可靠的高分辨距离信息。

| Abstract: | Chirp signal is employed by stepped-frequency chirp signal instead of simple pulse signal. In the processing of frequency-stepped signal, the method based on coherent spectnma synthesis makes a solution to the problem of range ambiguity. And the probability of false images is decreased caused by the conventional IFFT processing. Analysis and simulation results show that with the reasonable design parameter, effective pulse synthesis and high-resolution range profile in the frequency-stepped signal processing could be achieved. |
