| 摘 要： | 根据航空搜潜声呐浮标与飞机的相对方位信息，采用格型扩展卡尔曼滤波技术，对航空浮标定位方法进行了研究，建立了状态简化的2-状态定位系统的数学模型；利用蒙特卡洛仿真法，从位置估计的相对误差和均方误差两个方面，仿真分析了系统的误差性能，并获得了较好的效果。

| Abstract: | According to the relative orientation information received between the airplane and aerial anti-submarine buoy, the lattice extended kalman filtering technique is used to research the buoy location method. The mathematical model for the simplification of two-state location system is established. By using Monte-Carlo simulation arithmetic, the relative position errors and RMS error about position estimation and the system uncertainty are simulated and analyzed, Better tesults have been acquired. |
