大地电磁测深法中的静位移是国内外专家十分关注的问题,虽然提出了多种解决方案,但各种方法都有其效果与弊端.从大地电磁场基本理论出发,讨论了大地电磁测深法及其衍生方法的静位移问题,并提出了一种改进的大地电磁场静位移校正方法,利用最优估计和迭代的思路将平面聚类法和首枝重合法结合起来,解决不同成因产生的静位移效应,并使其完善为能够实现大规模资料处理的方法.使用理论模型响应验证了该方法的正确性,并且通过实测数据的应用结果与已知信息的对比分析,验证了方法的有效性.
The static displacement in the earth electromagnetic sounding method is a very concerned issue of domestic and foreign experts, and although a variety of solutions have been proposed, various methods have their effects and disadvantages.According to the basic theory of the earth electromagnetic field, Method and its derivation method, and proposes an improved static displacement correction method for the geomagnetic field. By using the idea of optimal estimation and iteration, the planar clustering method and the first branch coincidence method are combined to solve the problem of static displacement caused by different causes Static displacement effect and improve it as a method to achieve large-scale data processing.Using the theoretical model to verify the correctness of the method, and by comparing the application of measured data with known information to verify the effectiveness of the method Sex.
