This repository contains a MATLAB implementation for the one-dimensional (1-D) inversion of transient electromagnetic (TEM) data. Data (currently $\partial_t B_z$) can be either synthetic or real, e.g., as measured by the Geonics Ltd. PROTEM receiver using …

Multimodal Layered Transdimensional Inversion of Transient Electromagnetic data with Depth Constraints. (Can be used for all ground-based TEM survey designs, see parameter list below) The MuLTI-TEM algorithm was writted by Siobhan Killingbeck and Phil Livermore in 2019, School of Earth and Environemnt, The University of Leeds.

2016年7月8日 · We present a generic 1D forward modeling and inversion algorithm for transient electromagnetic (TEM) data with an arbitrary horizontal transmitting loop and receivers at any depth in a layered earth. Both the Hankel and sine transforms required in the forward algorithm are calculated using the filter method.

2021年4月1日 · In this study, we examine the feasibility of using deep convolutional neural networks for the inversion of marine frequency-domain controlled-source electromagnetic (CSEM) data as well as onshore time-domain electromagnetic (TEM) data. Our approach yields accurate results both on synthetic and real data and provides them instantaneously.

2021年3月20日 · 瞬变电磁法(Transient electromagnetic methods)是时间域电磁法之一(Time domain electromagnetic methods)简称TEM，属于地球物理电法勘探，是一种以电磁感应原理为基础的时间域人工场源的电磁勘探方法。

2023年9月24日 · 在地球物理勘探领域，瞬变电磁法（tem）是一种非侵入性且高效的探测技术，其核心在于通过分析电磁场随时间变化的特性来研究地下的物理性质。 当电流在导体中流动时，会产生一个稳定的磁场；若电流突然中断，由于电磁...

**瞬态电磁法（TEM）简介：** 瞬态电磁法是一种地球物理勘探技术，它通过发射一个周期性的电流脉冲到地面或水下，然后测量地下介质对这一脉冲电磁场产生的响应变化来探测地下结构。 TEM技术常用于矿产资源勘探、地下水勘查、工程地质调查等领域。 **一维反演的含义：** 一维反演假设地下结构在水平方向上是均一的，只在垂直方向上发生变化。 这种方法在处理实际问题时通常可以大大简化计算量。 在TEM数据处理中，一维反演尝试从测量到的电磁场变化时间序列 …

Toy Occam inversion code for 1D TEM (central loop) method in Matlab. The example data are from the forward modelling of a synthetic model (examples/true.mod) The forward modelling algorithm is an approximate method called ABFM (Adaptive Born Forward Mapping) from Christensen, 2002: Christensen N. B. (2002).
