摘要
该文针对野外地面导航系统受到环境未知、多源干扰的问题,设计具有环境适应能力与抗干扰能力的仿生偏振组合导航系统.首先引入仿生偏振导航技术,组成无重置型联邦滤波结构的仿生偏振/MIMU/GPS组合导航系统,建立各子系统的干扰模型;其次,为提高系统对于动态未知环境的适用性与抗干扰性,利用联邦滤波器优越的容错能力,设计系统针对几种组合模式的智能切换方案,有效检测并隔离GPS干扰子系统,实现可用系统的重构.
Abstract
This article focuses on the problem of unknown environment and multi-source interference in field ground navigation systems,and designs a biomimetic polarization integrated navigation system with environmental adaptability and anti-interference ability.Firstly,the bionic polarized-light navigation technology is introduced to form the bionic polarized-light/MIMU/GPS integrated navigation system without reset federal filter structure,and the interference model of each subsystem is established.Secondly,in order to improve the applicability and anti-interference ability of the system for dynamic unknown environments,utilizing the superior fault tolerance ability of federated filters,intelligent switching schemes for several combination modes are designed to effectively detect and isolate GPS interference sub-systems,and achieve the reconstruction of available systems.
