摘要
在分析惯性导航系统(INS)、合成孔径雷达(SAR)和地形匹配导航系统(TRN)各自特点的基础上,提出了INS/SAR/TRN组合导航系统的组合滤波方案,并建立了相应的组合导航系统数学模型。仿真结果表明,组合导航系统能大幅度提高导弹的导航精度,具有重要的实际意义。
According to the respective characteristics of Inertial Navigation System (INS), Synthetic Aperture Radar (SAR) and Terrain Referenced Navigation (TRN) system, an integrated filtering scheme of INS/SAR/TRN integrated navigation system is proposed, and the corresponding mathematic model is built. The result of simulation indicates the integrated navigation can greatly improve the navigation precision of missile and has profound practice significance.
