干扰条件下的雷达动态威力范围仿真方法

Radar Dynamic Detection Range Simulation Method in Jamming Circumstance

三维雷达探测威力范围仿真要求能够对雷达的电磁场景进行逼真的模拟,针对传统的雷达探测威力仿真方法不能动态显示的缺点,提出了一种基于STK仿真软件的动态可视化仿真方法。首先介绍了Matlab插件的功能及编程逻辑,然后分别对压制干扰条件下的雷达威力范围和干扰型无人机的飞行航迹进行了细致的数学建模,最后给出了动态可视化仿真的实现方法。该方法以STK为底层场景构建平台,通过Matlab插件在时域上采集雷达最大探测距离的边界数据,实现了动态的雷达三维探测威力范围的可视化。仿真结果表明,干扰机与目标雷达的距离越近压制效果越好,同时2部干扰机能够弥补单部干扰机进行干扰时的不足。仿真结果与理论分析具有一致性,验证了数学模型的正确性和仿真方法的有效性。

The simulation of the three-dimensional radar detection power range is required to be able to realistically simulate the radar electromagnetic scene. Aiming at the disadvantage that the traditional radar detection range simulation method cannot be dynamically displayed, a dynamic visual simulation method based on system tool kit (STK) simulation software is proposed. First of all, the function and programming logic of the Matlab plug-in are introduced. And then detailed mathematical modeling of the radar detection range and the flight path of the jammers are carried out. Finally, the realization method of dynamic visual simulation is given. This method uses STK as the bottom scene to build a platform. The Matlab plug-in collects the boundary data of the radar′s maximum detection distance in the time domain, and realizes the visualization of the dynamic radar three-dimensional detection range. The simulation results show that the closer the distance between the jammer and the radar is, the better the suppression effect is. At the same time, the two jammers can make up for the shortcomings of the single jammer. The simulation results are consistent with the theoretical analysis, verifying the correctness of the mathematical model and the effectiveness of the simulation method.
