| 摘 要： | 通过对水下纯方位目标运动分析中的扩展卡尔曼滤波(EKF)算法的分析,利用方位新息,构成了一条反馈回路,从而将EKF算法改进为变增益扩展卡尔曼滤波(VGEKF)算法.对比仿真分析表明,VGEKF较之EKF滤波效果有所改善,增强了稳定性,提高了精度,为水下纯方位目标运动分析的实现提供新的途径.

| Abstract: | After the analysis of EKF,the algorithm of underwater bearingsonly target motion analysis is improved from EKF to VGEKF through establishing another loop of feedback using azimuth innovation.The simulation results demonstrate that the VGEKF has better performance than the EKF both in stability and precision.A new method is provided for the realization of underwater bearings-only TMA. |
