摘要/Abstract

摘要： 现存的组合导航系统存在诸多问题：地形辅助导航系统分辨率较低；GPS/INS导航系统中GPS信号易受干扰；SAR/INS导航系统无法实现三维定位且无法获得平台的姿态信息.针对以上问题本文提出了基于条纹匹配的InSAR/INS组合导航方法：该方法将InSAR系统获得的干涉条纹与DEM生成的干涉条纹进行匹配，得到的定位偏移用以反演平台的位置和姿态信息，最后将反演结果与IMU信息进行组合滤波得到导航输出.该组合导航系统有以下优势：干涉条纹中包含地形信息和平台姿态信息；干涉相位对横滚角敏感，可通过干涉相位高精度反演平台的横滚角；InSAR系统具有较高精度的三维定位能力.本文主要介绍了基于条纹匹配的InSAR/INS组合导航的原理和方法，最后通过仿真和实测数据验证了条纹匹配和观测量反演算法的可行性.

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.

Key words: InSAR/INS integrated navigation, fringe matching, the inversion of observation volume, combined filter
