| 摘 要： | 对双站测向无源定位跟踪方法进行了研究,分析了双站交叉定位的基本原理,采用扩展卡尔曼滤波对三维空间中的机动目标无源定位跟踪问题进行了仿真分析。仿真结果表明,在假设的仿真条件下以及测向精度为0.001rad时,对机动目标定位跟踪的相对测距误差保持在2%以下,滤波跟踪效果良好,表明该方法对无源定位跟踪是有效的,对工程应用有一定指导意义。

| Abstract: | Dual-observer bearing-only passive location is researched and the foundamental of two station triangulation are analyzed in this paper.Maneuvering air target tracking is simulated based on extended kalman filtering.Simulation results show that using the method can locate maneuvering target.When measurement accuracy was at 0.001rad,relative ranging measurement error was below 2%.The simulation results prove that the method is feasible in passive tracking.It is valuable in engineering application. |
