摘　　要：简要介绍了三点垂直线阵被动定位的原理.结合矢量水听器测得的方位角和高低角及到达阵元间的时延差,建立了三维坐标下的状态方程和观测方程.运用扩展卡尔曼滤波算法,研究了该系统的目标运动分析问题.通过蒙特卡洛模拟仿真试验,结果表明上述方法具有较高的定位性能,有较强的使用价值.A brief introduction of vertical linear array is presented in this paper. According to the angle information measured by vector hydrophone and the time delays between points,three dimensional equation of state and equation of measurement are established. The target tracking algorithm is discussed using Extended Kalman Filter. It is demonstrated by the Monte-Carlo simulation results that the algorithm has better performance.
