摘要:

介绍了线性调频、非线性调频、相位编码3种脉冲压缩信号的基本原理以及每个信号的数学模型。在Matlab的仿真基础上,设定相同的参数下,通过对脉压幅度和主副瓣之比的分析,比较出3种雷达脉冲压缩信号的脉压效果。比较发现正弦调频信号的效果最佳。

关键词: 脉冲压缩, 线性调频, 非线性调频, 相位编码

Abstract:

In this paper,linear frequency modulation (LFM) signal,non-linear frequency modulation (NLFM) signal and phase-coded signal are applied in pulse compression radar system.The basic principles and the mathematical model of these three signals are introduced.Based on the MATLAB simulation,the pulse compression effect of the three types of radar pulse compression signals can be compared by analyzing the pulse compression amplitude and the mainlobe-tosidelobe rate with same parameters.

Key words: pulse compress;linear frequency modulation;non linear frequency modulation;phase code
