Title:
THREE-DIMENSIONAL COLLECTION METHOD AND APPARATUS FOR MAGNETOTELLURIC DATA, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036780
Kind Code:
A1
Abstract:
Provided are a three-dimensional collection method and apparatus for magnetotelluric data, and a terminal device. An interference zone center point is used as the center of symmetry, multiple points having a symmetric relationship therebetween are used as reference points, and electromagnetic data, which is synchronously collected by a collection device, of all the reference points and all measurement points is received, such that an existing step of collecting electromagnetic data of a remote reference point is changed to: collecting the electromagnetic data of the multiple reference points having a centrosymmetric relationship on the basis of the interference zone center point, and then performing time sequence superposition processing on the received electromagnetic data of the multiple reference points to obtain standard time sequence data. The obtained standard time sequence data is equivalent to electromagnetic data of the interference zone center point according to an electromagnetic field signal superposition principle, that is, an average electromagnetic field value of two points is equal to an electromagnetic field value of a middle point, thereby obtaining a signal that is fully associated with an interference zone signal.
