地磁匹配导航技术是跨海飞行器的自主导航方式之一。海洋磁场强度平滑、区域变化较大的特点，使，得飞行器一维地磁匹配方法难以应用于飞行器自主导航。在跨海飞行器组网条件下，讨论了多维地磁匹配相关度算法，并仿真计算了多维地磁匹配相关度的匹配时间、匹配概率，计算表明多维地磁匹配相关度算法优于单航迹匹配相关度；在相同概率下区域内370m×370m网格匹配时间短、匹配概率高。飞行器组网多维地磁匹配钓相关度算法研究为海洋区域地磁匹配导航应用提供参考。

The multidimensional geomagnetism field matching Mean Absolute Difference （SMAD） algorithm was constituted, and navigation was presented. The Synthesis it was estimated the correlation character of the multidimensional geomagnetism field matching navigation. The matching time and matching probability were simulation. At the same time, the Synthesis Mean Absolute Difference （SMAD） algorithm was excelled the single flight path matching correlation. The matching probability more highly and the matching time more short at used the matching areas 370 m×370 m. The correlation of SMAD method was based of project application of the multidimensional geomagnetism field matching navigation.
