摘要
米林顿算法是国际上比较常用的预测罗兰C信号场强和附加二次相位因子(ASF)的算法。本文首先介绍了该算法的基本原理和计算流程;然后在海上实验的基础上对该算法的理论预测数据和实测数据进行对比。根据对比结果,分析该算法在我国近海部分区域罗兰C信号预测中的性能,并指出改进的方向。
Millington ＇s method is generally used for forecasting the field strength and ASF of Loran C signal, This paper firstly introduces the basic theory of Millington＇s method, and then compares the theoretically forecasted data and the data collected from sea trial. According to the results of comparisons this paper analyzes the performance of Millington＇s method in forecasting ASF and Loran C＇s field strength.. At last, this paper gives the improving direction of Millington＇s method.
