基于多无人机协同的组网雷达轨迹欺骗干扰

组网雷达系统是应用两部或两部以上空间位置互相分离而覆盖范围互相重叠的雷达来实施搜索、跟踪和目标识别的系统。为了对组网雷达系统实施有效干扰,可以利用多无人机协同生成欺骗干扰轨迹。无人机生成的欺骗干扰轨迹数目越多,对组网雷达产生的干扰越大。因此,应在保证轨迹合理有效的前提下,尽可能多地生成虚假目标轨迹。因此,运用无人机空间运动方程建立无人机空间运动模型,通过空间位置的平移变换,在原有轨迹的基础上生成新的合理的虚假轨迹。结合空间内各点的位置关系和限定条件,将对空间运动模型的求解转化为对空间立体几何的求解,简化了运算过程。通过计算可知,9架无人机除生成1条原有合理轨迹外,还可形成3条虚拟轨迹。

Trajectory Deception Jamming of Radar Network based on Multi-UAV Cooperation

Radar network system is a system that performs search,tracking,and target recognition by applying two or more radars whose spatial positions are separated from each other and whose coverage ranges overlap each other.In order to implement effective jamming to radar network system,multi-UAV can be used to generate deceptive jamming trajectory.The more the number of deceptive jamming trajectories formed by Unmanned Aerial Vehicles(UAVs),the greater the jamming to radar network.Therefore,it is necessary to generate as many false target trajectories as possible on the premise of reasonable and effective.In this paper,the space motion model of the UAV is established by using the space motion equation of the UAV.Based on the original trajectories,the new reasonable false target trajectories are generated by the translation transformation of spatial position.Combined with limited conditions and the position relationship of each point in the space,the solution of the spatial motion model is transformed into the solution of the spatial solid geometry,which simplifies the operation process.Finally,the results indicate that in addition to forming the original one trajectory,three false target trajectories can be formed.
