摘要
简要回顾了地磁信息的使用现状,介绍了地磁信息的特征及其优缺点,在此基础上分析了地磁匹配的基本原理。考虑到实时地磁测量信息和经典地磁模型上的差异,在某些假设条件成立的情况下利用理想地磁模型进行了仿真计算,并从地磁匹配区网格大小、网格顶点磁强度差和高程控制3方面分析了现阶段地磁信息应用于巡航导弹组合制导的可行性,最后对误差源进行了分析。
The advantage and disadvantage of the geomagnetic information are introduced in the first part.Then the application of the geomagnetic information are retrospected.On this basis,the principle of the magnetic field contour matching are given.Concerned as the differences between the international reference geomagnetic field and the information of the survey to the magnetism,the theortic magnetic field position model is established under some hypothesis.The flight height control accuracy is calculated and the ...
