| 摘 要： | 早期雷达系统中存在着非常典型的难题,即检测能力与分辨率的矛盾.脉冲压缩为解决这一问题提供了有效的技术途径.线形调频信号脉冲压缩,因其较好的解决了雷达分辨力同平均功率间的矛盾,在近年来的雷达系统中被大量应用.文中主要讨论多普勒频移的产生原因及其对线形调频信号脉冲压缩的影响,用Matlab软件仿真了一个线性调频信号,在不同多普勒频移下的脉冲压缩的结果,并对这种影响加以分析.结果显示在多普勒频移的影响下,脉压结果仍有很好的主副辨比.

| Abstract: | The antinomy of power and resolution is a very typical problem to the radar system in the early days,and the technique of pulse compression offers an effective technical solution to this problem.The linear frequency modulation signal pulse compression has been widely applied in the radar system in recent years because it has solved the antinomy of average power and resolution.This paper discusses the reason for creating Doppler frequency shift and its effect on linear frequency modulation signal pulse compr... |
