多无人机在组网雷达中的虚假目标轨迹生成

False Target Trajectory Generation of Multi-UAV in Radar Network

组网雷达系统具有较强的抗干扰能力,如何对组网雷达实施行之有效的干扰,是当今电子对抗界面临的一个重大问题。多无人机对组网雷达的协同干扰是近年来新兴的一种雷达干扰方式。通过协同控制无人机的飞行轨迹,可在敌方的组网雷达系统中形成一条或多条欺骗干扰轨迹,迫使敌方加强空情处置,达到欺骗目的。主要研究如何利用最小数目的无人机生成虚假目标轨迹,从而对组网雷达实施有效的干扰。运用禁忌搜索的方法,根据无人机的限定条件,建立最小化无人机数目模型,通过对坐标点的遍历,进而分析出无人机合理的运动轨迹,并且计算出无人机在运动过程中被雷达探测到的位置的坐标。最后得出至少可以用33架无人机生成给定虚假目标轨迹的结论。

Radar Network system has strong anti-jamming ability.How to implement effective jamming to radar network is a major problem in the field of electronic countermeasures.Cooperative jamming of multiple Unmanned Aerial Vehicles(UAVs)to radar network is a new radar jamming mode in recent years.By planning the trajectories of UAVs,one or more deceptive jamming trajectories can be formed in the enemy’s radar network system,which forces the enemy to strengthen the air situation disposal and achieve the purpose of deception.This paper mainly studies how to use the minimum number of UAVs to generate false target trajectory,so as to implement effective jamming to the radar network.Using the method of tabu search,according to the limited conditions of UAVs,the model of minimizing the number of UAVs is established.Through the traverse of coordinate points,the reasonable trajectories of UAVs are analyzed,and the coordinates of the position detected by radar during the movement of UAV are calculated.The results indicate that at least 33 UAVs can be used to generate the given false target trajectory.
