摘要
提出一种以重力异常图重构为基础的辅助潜艇水下定位的方法。着重介绍了重力异常图的拟合细分,并分析了利用Carpenter/Grossberg分类器对匹配点进行分类,选出最佳匹配点的匹配算法。仿真结果表明,利用重力异常图重构的方法,匹配辅助潜艇水下定位能够达到较好的效果,完全满足高精度导航的需求,具有一定的可行性。
A method for submarine positioning underwater based on restructure of gravity abnormity map is brought forward. The fitting subsection of gravity abnormity map is emphasized. The matching arithmetic that Carpenter/Grossberg classifying instrument classifies the matching points, and then the optimal matching point is singled out. The simulation result shows that the method has good effect for submarine positioning underwater based on the restructure and matching of gravity abnormity map, it suits navigation of high precision, and it is feasible to some extent.
