基于条纹匹配的InSAR/INS组合导航方法
The Method of the InSAR/INS Integrated Navigation Based on Fringe Matching
摘要
Abstract
The existing integrated navigation systems have lots of problems:the resolution of the terrain aided navigation system is low;the GPS signals of the GPS/INS navigation system are susceptible to be interfered;the SAR system has no ability of three-dimensional localization,and it cannot inverse the attitude of the platform.Aiming at the above problems,this article presents the method of InSAR/INS integrated navigation system based on the fringe matching.In the integrated navigation,we can obtain the location shift by matching two interference fringes,one is produced by InSAR system and another is generated by the digital elevation database.With the aid of the location shift we can inverse the attitude and position information.The location shift and the IMU information are set to the combined filter to obtain the navigation output.The InSAR/INS system has the following advantages:the interference fringes include the terrain and the attitude information of the platform;the interferometric phase is susceptible to the roll angle and we can inverse the roll angle by the phase with high precision;the InSAR system has the ability of three dimension localization.In this article,we introduce the theory and method of the InSAR/INS integrated navigation based on fringe matching.At last,we verify the validity of fringe matching and the inversion of observation volume by simulation and real data.关键词
