无人机电子干扰条件下的路径规划

针对机载预警雷达结合地面雷达对低空突防无人机构成的严重威胁,提出一种基于A*算法的路径规划算法.该算法分析了电子干扰和无人机RCS对雷达探测空间的影响,建立了新的雷达探测空间模型和威胁模型进行路径规划,将A*算法应用于无人机的路径规划过程.在此基础上给出了应用该方法的具体步骤,并进行了MATLAB仿真.仿真结果表明:考虑电子干扰对雷达威胁区域影响的情况下规划的飞行路径飞行器能有效回避威胁,有效提高无人机的低空突防能力.

UAV Path Planning Under the Electronic Jamming Condition

Based on the A* algorithm to design the optimal trajectory,which present to solve the severity threat that the AEW(Airborne Early Warning)and ground radar constitutes to the UAV of the low altitude penetration. This algorithm Analyzes the influence of Electronic Jamming exercises and UAV's RCS on the radar detecting space. New radar detection space equation and threat model are established, A*algorithm is used to design the optimal path planning of UAV.Under the result of the software simulation of flight route planning based on MATLAB is practicable by considering the electronic Jamming exercises influence on threat zone of radar, can advance the ability of the low altitude penetration of UAV effectively.
