扫频干扰对捷变频雷达干扰效能仿真分析

摘要

捷变频雷达是一种抗干扰能力很强的新体制雷达，而扫频干扰是干扰捷变频雷达的一种有效方式。首先分析了捷变频雷达的主要特性，并对扫频干扰对抗捷变频雷达的技术条件进行研究，然后建立随机捷变频雷达被干扰概率仿真计算模型，运用Matlab仿真软件进行实例计算，分析了影响扫频干扰雷达的干扰效能主要因素和非影响因素，得出一些有利于雷达和干扰机进一步改进的结论。%Frequency hopping radar is a kind of new system radar whose anti⁃interference ability is very strong. Sweep jam⁃ming is an effective way to interfering frequency hopping radar.First of all,the main characteristics of frequency hopping radar were analyzed.And the technology conditions of sweep jamming against frequency hopping radar were studied.Then the proba⁃bility formulas calculation model of random frequency hopping radar was built. Through example calculation, the paper analyzes the main factors and XX factors of sweep jamming for affecting radar.At last,a series of conclusion were obtained which can help radar and jammer to improve in future.
