摘要
针对现有的水下地磁匹配导航算法误匹配率较高的问题,提出一种改进的水下地磁匹配导航算法。该算法在传统点搜索的基础上,通过采集多个特征值并配合粗精策略,达到了降低误匹配率的目的。结合惯导系统对该算法进行仿真分析,仿真结果表明,该算法可以有效的降低误匹配率,提高了匹配的精确性,具有一定的工程应用价值。
For reducing the high false matching rate of geomagnetic matching algorithm for underwater navigation, an improved geomagnetic matching algorithm was proposed. Based on the traditional point search algorithm, this algorithm reduces the false matching rate through multi-features and the coarse fine strategy. After doing the simulation combined with the inertial navigation system, the result shows that this algorithm reduced the false matching rate of geomagnetic matching navigation effectively and improved the accuracy, and this algorithm is suitable for engineering application.
