target-tracking-in-three-dimensional
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.
(Introduced three vertical linear array passive location principle of vector hydrophone. Combining the measured azimuth angle and pitch angle and arrival time delay difference between array elements, establish the three-dimensional coordinates of the state equation and observation equation. Using the extended Calman filter algorithm, on the target motion analysis by Monte Carlo simulation. Test, results show that the method has high positioning performance, has the strong use value.)
