| 摘 要： | 通过观察船模在不同航向下所产生的磁场,得到磁场与航向存在正余弦关系,在磁场数学建模的基础上推导分析认为,能通过测量两个不同航向下的磁场估计任意航向下的磁场,减少实测次数,而且可用于识别航向。

| Abstract: | Through the data of ship's magnetic field in different directions,we got the sine relations between the ship's magnetic field and the ship's direction,and proved based on the model of ship's magnetic field.Using this method that we only need two ships' magnetic field survey experiments with different direction,there was confirmed that we could estimate data of ship's magnetic field in all directions in the theory and could reduce the times of survey experiments,also was good for identifying the ship's direction. |
