摘要
利用海底地形辅助导航是水下载体导航技术致力研究的新方向,在利用多波束测深系统测量真实地形数据的基础上,采用SITAN算法作为对准匹配算法,对传统的SITAN算法加以改进,进行仿真计算,得到水下载体的最佳匹配位置,以提高水下载体的导航精度。仿真结果表明,改进后的SITAN算法更能满足导航的精度要求。
Terrain matching assistant navigation is a new method in navigation technology of the underwater vehicles.In this paper,the real terrain data are measured by Multi-beam sounding system,and SITAN algorithm is selected as a registration matching algorithm.Furthermore,the algorithm is developed based on the conventional SITAN algorithm.Based on the measured terrain data and the algorithm,the accumulative errors of the inertial navigation system can be corrected and the optimal matching position can be gotten.I...
