Abstract
The time-frequency electromagnetic method is a controlled-source electromagnetic method, which has a strong anti-interference ability and a high resolution for the electrical layer in the middle and shallow layers. However, it is limited by the lowest excitation frequency and has a limited reflection of the deep layer. The magnetotelluric method is a natural source electromagnetic method, which features low measurement frequency and large detection depth. Hence, the two methods are complementary. In this paper, on the basis of Occam's inversion algorithm, a new joint weighting method is proposed for the joint inversion between time-frequency electromagnetic and magnetotelluric data. The data of model and field tests show that the joint inversion of time-frequency electromagnetic and magnetotelluric data can improve the resolution of shallow electrical anomalies, optimize the detection accuracy of deep electrical layers, and improve the ability of electromagnetic exploration to solve geological problems.
