在大地电磁张量阻抗估算中广义逆矩阵法的研究与应用

本文论述大地电磁测深中非均匀介质中估算张量阻抗几种方法的实质,着重讨论用广义逆矩阵法估算张量阻抗,用信息矩阵压制相关噪声以及度量相关噪声水平高低的判断指数。最后,指出各种方法的不足及改进措施。

STUDY AND APPLICATION OF THE GENERALIZED INVERSE MATRIX MOTHOD IN MAGNETOTELLURIC IMPEDANCE COMPUTATION

In this paper,several mothocis of impedance computation in non-uniform medium are analysed.lt is emphatically discussed to-use the Generalise Inverse Matrix Mothod in impedance Computation,to use the Information Matix to suppress cohereut noise and to define judgement indicator to measure the Level of coherent noise.At Last,the author poiuts out the saetteomiugs of various mothods and their improverrieuts.
