摘要
当前电磁环境日益复杂,对多个辐射源的数据关联和无源定位已经成为重要的研究方向。以时差双曲交会定位为例,根据不同时刻到达时间差的连续性以及同一目标到达不同监测站时间差之间的相关性,完成测量数据的正确关联,并利用卡尔曼滤波、扩展卡尔曼滤波、粒子滤波对辐射源的位置进行估计,仿真计算表明该方法具有较高的正确关联概率,可以实现定位误差的快速收敛。
With the development of electronic environment,data association of multi-target and passive localization has become one of the most popular research hotspots.Taking time difference hyperbolic intersection localization for example,according to the continuity of arrival time difference at different time as well as relativity among the time differences which the same source arrives at different monitoring stations,a correct association of measured data is realized and Kallman filtering,expanded Kallman filtering and particle filtering are used to realize the passive localization.The simulation shows that the proposed method has a high correct probability of association and can realize a fast convergence of localization error.
