基于海洋磁异常特征的目标定位理论和方法

Localizing Theory and Method Based on Maritime Magnetic Anomaly Features

在世界磁场模型WMM2005的基础上,建立了海洋磁场的数值计算模型,根据水下目标磁场的远场分布特征,建立了目标磁场分布的定位模型。在此基础上提出了水下目标磁异常定位方法。仿真实验证明,该定位方法完全可以满足水下目标精确定位的要求。

On the basis of the world magnetic model 2005 ,the ocean magnetic field model was derived,a target magnetic anomaly localizing model was presented based on the features of long distance field, a localizing method was given. Simulated results confirmed that the underwater target localizing accuracy accorded the requirement.
