It is well-known that geomagnetic fields have multiple components or parameters, and that these geomagnetic parameters are related to each other. In this paper, a parameter selection method is proposed, and this paper mainly discusses the correlation of geomagnetic field parameters for geomagnetic navigation technology. For the correlation analysis between geomagnetic parameters, the similarity calculation of the correlation coefficient is firstly introduced for geomagnetic navigation technology, and the grouped results are obtained by data analysis. At the same time, the search algorithm (Hex-path algorithm) is used to verify the correlation analysis results. The results show the same convergent state for the approximate correlation coefficient. In other words, the simulation results are in agreement with the similarity calculation results.
众所周知，地磁场具有多个分量或参数，并且这些地磁参数相互关联。本文提出了一种参数选择方法，主要讨论了地磁导航技术中地磁场参数的相关性。对于地磁参数之间的相关性分析，首先引入相关系数的相似性计算用于地磁导航技术，并通过数据分析得到分组结果。同时，使用搜索算法（六边形路径算法）来验证相关性分析结果。结果表明近似相关系数具有相同的收敛状态。换句话说，模拟结果与相似性计算结果一致。
