Design and implementation of the algotithm of radar signal with the charactericstic of antenna scanning

在暗室中,搭建雷达导引头抗干扰性能测试所需的复杂电磁环境具有一定难度,其中目标雷达发射信号的产生尤其困难;对此提出了一种具有天线扫描特性的雷达发射信号产生算法。首先,分析了雷达天线方向图类型和天线扫描方式,并建立了对应数学模型;其次,将建立的数学模型与雷达方程结合,提出了雷达发射信号功率计算法;最后,以该算法为基础开发雷达信号模拟软件,并借助于矢量信号发生器生成具有天线扫描特性的雷达发射信号。测试结果表明,该算法产生的雷达信号具有天线扫描的特性,为暗室环境下导引头抗干扰性能的测试提供了信号保障。

In the dark room,It is difficult to build complex electromagnetic environment to test the performance of radar seekeranti-interference,espciallyproducting the target radar signal with the antenna scanning features;In this paper,thealogrithm of radar signal with the antenna scanning features was proposed.First,the radar antenna pattern types and the antenna scaning mode were analyzed,and the corresponding mathematical models were built;Second,the mathematical models and radar equation were combined to put forward the radar signal power calculation method;Finally,Base on the mathod the radar signal simulation software was developed,andthe radar signal was generated by vector signal generator.The test shows that signal has the feature of antenna scanning and provides protection for testing the radar seeker anti-interference in the darkroom.
