摘　　要：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。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.

关 键 词：高距离分辨率 低截获概率 步进频率脉冲串信号 相位编码信号
