线性调频信号和噪声调频信号性能对比分析

Analysis of The Performance Comparison between LFM Signal and Noise FM Signal

介绍了线性调频信号、噪声调频信号和匹配滤波的原理,对线性调频信号和噪声调频信号进行了时频域计算机仿真,并对两种信号加窗前后脉冲压缩的主副比、主瓣展宽等进行了对比分析,总结了两种调频信号的适用性。

This paper introduces the principle of linear frequency modulation(LFM)signal,noise frequency modulation(FM)signal and matched filter,performs computer simulation of LFM signal and noise FM signal in time and frequency domain,makes comparison analysis to the main/side-lobe ratio and main-lobe widening of pulse compression before and after windowing processing for two signals,and summarizes the applicability of two FM signals at last.
