| 摘 要： | 根据被动观测器所测得的目标方位和多普勒频率信息,通过对新息的伪线性处理,建立了系统线性的状态方程和观测方程,并推导出修正的扩展卡尔曼滤波递推公式,从而对目标的运动状态进行估计。通过蒙特卡罗仿真表明,此算法具有收敛速度快、精度高、稳定性好等优点,可应用于远距离的水下被动目标运动分析。

| Abstract: | Base on the measurement of both bearings and frequencies by passive observer,the linear equation of both state and measurement are established through pseudolinear method applied to innovation and the modified extend Kalman filter is obtained and can be estimate the parameters of moving target.The Monte-Carlo simulation experiment results demonstrate that the MEKF algorithm has some merits of fast convergence,high precision and stability.So the algorithm can be applied to the long-range underwater passive TMA. |
