摘要
对目前生产实际中遇到的磁力探头水平位置改正方法进行研究和改进,通过合理利用船艏向数据,引入角度因子改进已有直接概算法,并结合拖曳概算法,形成改进的拖鱼水平位置改正方法。此方法是在已有改正方法的基础上获得,具有较好可靠性,且由于其计算方法不复杂,对输入数据要求不高,利于在实际生产中应用。通过模型和实测数据验证,该方法对提高磁测数据精度有一定效果,可以在今后处理任务中加以利用。
The paper studies the magnetic detector horizontal position correction method to improve directed financial estimate method by importing angle factor and combining drag financial estimates method based on the ship heading data,then we can obtain improved towfihs horizontal position correction method.This method is reliable and can be applied easily in the production due to its simple calculation.Finally we test the method by using model and measured data,and result shows that his method can effectively raise the ocean magnetic data precision,so we can use this method in the work.
