摘　　要：为了满足水下航行器高精度导航定位的需求,建立了多传感器组合导航的系统模型。针对信息融合过程中出现的非线性环节,在传统联邦滤波器的基础上,提出了基于粒子滤波的混合联邦滤波器。其中,线性子系统采用卡尔曼滤波算法进行滤波估计,非线性子系统采用粒子滤波算法进行滤波估计。计算机仿真分析表明,该混合联邦滤波算法能够将线性和非线性子系统的滤波结果很好地融合起来,提高了组合导航系统的定位精度。In order to meet the needs of high-precision navigation and positioning for the Autonomous Underwater Vehicle （AUV） ,the multi-Sensor integrated navigation system model is established. The mixed federal filter is proposed based on the traditional federal filter to aim at the non-linear course in the information fusion process. The Kalman filter is applied in the linear subsystem and particle filter is applied in the non-linear subsystem. The computer simulation results show that the linear and nonlinear filtering subsystem can be well fused together by the mixed federal filtering algorithm, and the navigation positioning accuracy is greatly improved.
