一种多源地磁数据融合处理方法

A combination method of geomagnetism based on multi-surface function

地磁辅助导航是一种重要的定位方法,其关键技术之一就是建立满足地磁导航所需要的地磁图。针对船测地磁数据覆盖面不足,且航测地磁数据延拓精度不高的问题,该文提出了一种以多面函数为基准对地磁测量系统误差进行建模的方法,以完成多源地磁数据的融合,并且通过仿真实验对算法进行了评价,验证了算法的有效性。

The geomagnetism aided navigation is an important method to localize the position.One of the key techniques is a high accuracy geomagnetism map that can meet the demands of navigation.This paper introduced a combined method which based on multi-surface function and building geomagnetic field model that described the system error.Then the simulations on the method were performed to evaluate the effect of the algorithm.
