摘要
该文提出了一种脉冲压缩的新方法—匹配傅里叶脉冲压缩技术。该方法可对多目标回波在匹配傅里叶域实现压缩.压缩回波峰值位置相对时延呈线性变化,从而使该方法与传统的脉冲压缩技术—匹配滤波器脉冲压缩一样,可在雷达信号处理中应用。文中首先给出匹配傅里叶脉冲压缩理论和脉冲压缩的回波时延分辨率,然后进行理论仿真验证.仿真结果表明该理论是正确的,所提出的方法是可行的。
A new method of pulse compression, match Fourier pulse compression technology is proposed in this paper. The method can achieve pulse compression to multi-targets'echoes in match Fourier domain, and the peak position of each compressed echo changes linearly with its time delay. The same as conventional method of match filter pulse compression, it can be applied to radar signal processing. The paper first gives the theory of match Fourier pulse compression and the resolution between echo time delays. Then the simulation is carried out. The results verify that the theory is right and the new method is feasible.
