双基阵纯方位水下被动目标跟踪性能仿真分析

研究了基于纯方位信息的双基阵声纳信息融合的跟踪性能，并进行了详细的仿真实验。仿真结果表明，在平台—目标相遇这种较为常见的态势下应用扩展卡尔曼滤波可以快速、稳定地完成目标运动要素的估计，同时还揭示了平台与目标运动的几何态势对跟踪性能的影响，为工程应用提供了参考。

Emulational Analysis on the Performance of Underwater Bearing-only Passive Target Tracking Using Two Arrays

The tracking performance of data fusion based on underwater bearing-only measurements of two arrays is studied in this paper. The simulation results show that the target motion analysis method with two-dimension bearing-only information have not only eliminated maneuvers needed by conventional bearing-only TMA based on single array, but also improved the stabilization and global convergence for estimation algorithm. The movement factors of target can be fast and steadily estimated under the usual situation of towarding the target using extended Kalman filter. At the same time, the influence of the geometrical situation of our ship to the target on the tracking performance is shown and references to engineering application are provided.
