一种高距离分辨率低截获概率的雷达信号分析

摘要

This paper presents a composite modulation signal based on an uniform pulse train, which uses two-phase coded intrapulse phase modulation and step frequency interpulse frequency modulation, through MATLAB simulation analysis, shows that this kind of signal has the advantages both of phase-coded signal and step-frequency signal, and makes up the shortcomings of these two signals, so it is a radar signal with high-range resolution and low probability of intercept.%提出了一种在均匀脉冲串的基础上,脉内采用二相编码进行调相、脉间采用步进频率进行调频的复合调制信号.通过MATLAB仿真分析,说明这种信号兼有相位编码信号、步进频率信号的优点,又弥补了这2种信号各自的缺点,是一种具有高距离分辨率、低截获概率特性的雷达信号.
