摘要
针对超视距目标指示问题,建立了基于大地坐标的目标运动方程和观测方程,并将UKF滤波方法运用于目标的跟踪。由多艘舰艇组成一个协同的目标指示系统,并将一种新的分布式融合算法运用于该系统,提高了目标的跟踪精度。仿真结果验证了该算法的有效性。
Concerning the problem of over the horizon target tracking,the target maneuvering model and measurement model based on geodetic coordinate were established,and UKF method was used in target tracking.A collaborative target indicating system was composed of several warships,and a new decentralized data fusion algorithm was used in this system.Because of that the tracking accuracy was improved.The simulation results show that the algorithm is efficient.
