摘要
文章提出了一种适于水下应用的海底地形匹配方案。介绍了该系统的原理及匹配算法。建立了海底地形辅助导航系统仿真模型,并进行了计算机仿真。仿真结果表明,海底地形辅助导航系统可以有效地抑制惯导系统的位置误差,提高导航精度。
In this paper, a seabottom matching scheme suital to underwater applications is presented. The principle of the sys tem and the matching algorithm is introduced. The simulation model about the Seabottom Seabottom System is established and sim ulation is executed. The results show that the position errors of the INS can be restrained effectivelly and the navigation accuracy can ben improved by the Seabottom Mapping System.
