论文摘要

在现代海战中,舰载雷达系统与机载雷达系统之间的对抗是电子战过程中的重要一环。本文针对雷达对抗中仿真中涉及的雷达截面积、距离方程、天线、仿真建模等关键理论和技术问题,进行了系统的分析和研究,设计了模拟对抗方案,编写了仿真程序,实现了典型作战场景的计算机仿真。首先,对雷达截面积的计算方法进行概述,分析多种算法的特点,采用矩量法和高频近似法计算了典型舰艇和飞机的雷达截面积。其次,对雷达系统建模理论和应用进行了深入分析,讨论了发射机、接收机、天线、探测与跟踪等关键分系统的建模方法；分别针对舰载雷达和机载雷达进行了仿真建模。最后,对典型飞机雷达截面积、导弹雷达截面积、微带贴片天线、阵列天线进行了建模仿真,编写了雷达搜索、雷达跟踪、攻击告警等动态仿真程序。
