线性调频相参脉冲雷达信号模糊函数仿真分析

Simulation and Analysis of LFM Coherent Pulse Radar Signal Fuzzy Function

根据线性调频相参脉冲信号模糊函数理论特点,对大时宽相参雷达脉冲序列模糊函数及投影图、时频域切片和副瓣电平进行了仿真计算,讨论了信号时频耦合、主副瓣性能与时间距离速度分辨能力,分析了相参体制雷达模糊函数钉板现象与截获性能。

According to the theoretical characteristics of fuzzy function of linear frequency modulated coherent pulse signal,this paper simulates and calculates the fuzzy function and projection diagram,time-frequency domain slice and sidelobe level of the pulse sequence of large-time-width coherent radar,discusses the signal time-frequency coupling,main/side lobe performance and time/range/velocity resolution capability,analyzes the thumbtack phenomenon and the interception performance of coherent radar fuzzy function.
