基于单椭球体舰船磁场模型的感固分离研究

舰船在地球弱磁场中的磁化过程是线性、可逆的，可以将舰船磁矩分为固定磁矩和感应磁矩。对于不同的舰船磁场数学模型，对其进行感固分离通常是采用不同的方法。通过对舰船的3个方向上的去磁系数进行分析，可以近似地将椭球体模型中的感应磁矩和固定磁矩分离开来。

Study on Separating Peg and Induce Magnetic Moment Based on the Ellipsoid Spheroid Magnetic Model

Because the ships＇ magnetization process in global magnetic field is linear and reversible, the ship＇ magnetic moment could be divided into the peg magnetic moment and induce magnetic moment. According to the mathematic model, a novel method was used generally in separating the peg magnetic moment and the induce magnetic moment. Through analysis about demagnetization factor in three direction of warship, the peg and induce magnetic moment of the ellipsoid spheroid model can be separated.
