基于两航向测量的舰船任意航向磁场计算方法

Calculating Method of Ship Magnetic Field on Any Course Based on Two Course Measurements

通过对舰船磁场特性的分析,提出了一种推算舰船任意航向三分量磁场的计算方法。在同一测量深度和测量点的前提下,该方法仅利用相反的两个非主航向上舰船三分量磁场实测数据,可直接计算出任意航向舰船三分量磁场,为分析研究任意航向舰船的磁特征和磁隐身性能提供了依据。实验验证了方法的可行性和准确性,该方法可推广应用于不同区域舰船三分量磁场的推算问题。

Through the analysis of the characteristics of the ship＇s magnetic field, a new method is proposed to calculate ship＇s three-component magnetic field on any course. On the premise of the same measuring depth and the same measuring point, and based on the proposed method, ship＇s three-component magnetic field on any course can be directly calculated by using the measured data of ship ＇s three-component magnetic field on two contrary courses while the data of the main course is no longer necessary. This method also provides reference for the study of ship＇s magnetic field characteristics on any course and magnetic stealth performance. The experimental results verify the feasibility and accuracy of the method. The：method can be applied to calculate ship＇s three-component magnetic field in different regions.
