电子干扰对低可观测飞行器飞行路径规划的影响

为了提高巡航导弹的低空突防能力,在分析电子干扰对雷达网威胁区域的影响后认为:在多重干扰条件下,雷达探测空间会顺着干扰方向产生内凹和偏移,因此,建立了新的雷达探测空间模型.采用空间对象间拓扑关系推理方法建立了飞行器飞行路径规划目标函数中雷达威胁指数模型,然后改进了飞行器飞行路径规划模型,并在此基础上进行了巡航导弹飞行路径规划的软件仿真.仿真结果表明:考虑电子干扰对雷达威胁区域的影响情况下规划的飞行路径能够回避雷达威胁,有效提高飞行器低空突防能力.

Electronic Jamming Exercises Influence on Flight Path Planning of Low Observation Aircraft

In order to advance the ability of the low altitude penetration of the cruise missile,this paper analyzes the following influence:under multi-jamming circumstance,radar detecting space can form inner concave along the direction of the electronic interference after assaying that electronic interference exercises influence on threat zone of the radar net,hence,this paper presents an new radar detection space equation.The new objective function and threat index of the flight path planning are rebuilt using topological relation reasoning among space objects.Based on the study,the software simulation of flight route planning of the cruise missile is fulfilled.The result of the software simulation demonstrates that the flight route is practicable by considering the electronic interference influence on threat zone of radar net.If the aircraft flies using this flight route,the ability of the low altitude penetration of the cruise missile is advanced.
