地磁导航中复合卡尔曼滤波应用发展研究
Study on Application and Development of Composite Kalman Filter in Geomagnetic Navigation
摘要
Abstract
Geomagnetic navigation,as an autonomous,passive,and highly concealed navigation method,has gar-nered significant attention in recent years within the fields of aerospace and underwater navigation.Composite Kalman filter,by integrating information from multiple sensors,can effectively suppress noise and enhance system robustness,making it one of the key technologies for improving the accuracy of geomagnetic navigation.The study first elucidates the fundamental principles of Kalman filter and identifies key challenges in implementing centralized filter for geomag-netic navigation,including framework constraints,high-dimensional data processing requirements,limited fault tole-rance,and scalability issues.Subsequently,it introduces two alternative approaches:distributed Kalman filter and Kalman filter augmented with auxiliary techniques,followed by a comprehensive analysis of composite filter implemen-tations in geomagnetic navigation systems.Finally,the prospects and future directions of composite Kalman filter in geo-magnetic navigation are summarized.关键词
