摘要
预警雷达反干扰闭环仿真对于研究雷达系统反干扰性能改进和新型干扰样式具有重要意义。为此,通过分析雷达干扰与反干扰信号仿真流程,构建雷达系统、典型干扰样式与反干扰措施的物理模型,设计了可闭环仿真密集假目标干扰、瞄频式干扰和扫频式噪声干扰等干扰样式以及雷达副瓣对消和副瓣匿隐等反干扰措施的全系统信号模型。通过与实装对抗试验结果进行对比,验证了仿真模型的有效性。
Surveillance radar antijamming closed-loop simulation is of great significance for researches on radar system antijamming performance improvement and new kinds of jamming patterns. Total system signal grade simulation model,which can simulate jamming patterns like dense false target jamming,frequency spot jamming,sweep frequency jamming,and antijamming measures such as sidelobe blocking,sidelobe cancellation etc.,is designed by analyzing the simulation process of radar jamming and antijamming signals,building physical models of radar system,typical jamming patterns and antijamming measures. The function of simulation model is proved effective by comparing with the results of real equipment tests.
