摘要

针对跨介质飞行器入水强瞬态冲击导致导航精度下降的问题，提出了一种弹道模型辅助的自适应扩展卡尔曼滤波（AEKF）导航误差修正的方法。通过建立跨介质飞行器的弹道模型和捷联惯性导航系统(SINS)输出飞行器的运动信息，并使用AEKF算法对导航误差进行估计，将估计的误差结果反馈到SINS进行导航修正

得出高精度的导航结果。仿真结果表明:本文提出的算法相较于无弹道模型辅助的扩展卡尔曼滤波（EKF）算法，导航性能显著提升，对于强瞬态干扰具有一定的适应性。

Abstract

A ballistic model-assisted adaptive extended Kalman filter (AEKF) navigation error correction method is proposed

to solve the problem of degradation of navigation precision due to strong transient shock when the trans-media aircraft enters water.By establishing the ballistic model of the trans-media aircraft

and using the motion information output from the strapdown inertial navigation system (SINS)

the AEKF algorithm estimates navigation error.The estimated error results are fed back to the SINS for navigation correction to obtain high-precision navigation results.Simulation results show that the proposed algorithm significantly improves the navigation performance compared to the extended Kalman filter (EKF) algorithm without ballistic model assistance

and demonstrates adaptability to strong transient interference.
