地磁匹配导航中适配区的选择

摘要

A reasonable geomagnetic adaptable matching area can improve the navigation accuracy effectively. The selection of geomagnetic adaptable matching area based on geomagnetic field character and on geomagnetic character parameter information entropy are compared. Through a particular case, it is shown that the selection based on geomagnetic character parameter information entropy is more effective and more appropriate as the standard of the selection of geomagnetic adaptable matching area.%对地磁匹配导航中适配区的选择进行了研究,给出了选择适配区的基本原则,研究了基于磁场特征参数和基于地磁特征参数信息熵的适配区选择方法,结果表明基于地磁特征参数信息熵的适配区选择方法更有效,更适合作为适配区的选择标准.
