人工源频域电磁法主要有原苏联提出的频率电磁测深]和欧美国家所提的可控源音频大地电磁法(CSAMT)]两种比较常用的勘探方法,两种方法的基本原理相同,只是在测量电磁分量和电阻率计算等方面略有差别。由何继善院士基于传统的可控源音频大地电磁法(CSAMT)和磁偶源频率测深法(MELOS)提出来的广域电磁法继承了CSAMT
Artificial source frequency domain electromagnetic method mainly consists of the former Soviet Union proposed frequency electromagnetic sounding] and Europe and the United States referred to the controllable source audio Magnetotelluric (CSAMT)] two commonly used exploration methods, the basic principles of the two methods are the same, Only a slight difference in the measurement of electromagnetic components and resistivity calculation and so on. The wide area electromagnetism proposed by Academician He Jishen based on the traditional CSAMT and MELOS inherits CSAMT
