分布式干扰下雷达探测区计算与仿真

针对导弹在飞行中段实现突防的电子干扰要求，提出了采用分布式星载有源干扰的方法来实现。为了有效计算各干扰机对目标雷达的干扰功率，巧妙利用空间两条直线的夹角公式，求得干扰机主瓣方向与该干扰机到雷达连线方向的夹角和雷达主瓣方向与雷达到各干扰机连线方向的夹角，从而将该方法从二维推广到三维。提出了有干扰和无干扰情况下，雷达探测区的通用公式。所提方法不仅适用于单干扰机对单雷达，也可用于多干扰机对多雷达场景。最后进行了详细的仿真分析，验证了理论分析的正确性和有效性。

Calculation and Simulation of Radar Detection on Distributed Satellite Jamming

In the middle of a missile flight to fulfill its penetration requirements of electronic jamming,The method of adopting distributed satellite actively jamming is proposed.In order to compute effectively the jamming power of every jammer on a target radar,using skillfully the angle formula of two space straight lines,we can obtain the angles between the direction vectors of main lobe of jammers and the di-rection vectors from the corresponding jammers to the radar and the angles between the direction vector of main lobe of the radar and the direction vector from the radar to the jammers,which extends the method from two dimension to three dimension.The general formula of the radar detection on jammers or not is proposed.The proposed method will not apply only to the situation of single radar in single jammer,but also to the state of multi-radars in multi-jammers.Finally,the detailed simulations given verify the ration-ality and validity of the theoretical analysis.
