The geophysical parameter inversion from magnetic anomalies data usually faces a non-linear optimization problem with multi-variable, multi-objective function extremum, multi-solution and so on. Therefore, it is necessary that the more stable and efficient algorithms is used in the geophysical inversion. Particle swarm optimization (PSO) has been used in the geophysical inversion. However, for high-dimensional,...
Geophysical optimized inversion of gravity data using genetic algorithm (GA) still faces some problems. It often divert to the local solution, causing premature convergence. Here, we present an optimized inversion method based genetic algorithm and generalized least squares (GLS) to estimation the model parameters of geological bodies. The synthesized gravity data is given for testing the performance...
Geoelectric stratigraphy recognition in transient electromagnetic (TEM) signal is presented on basis of time-frequency analysis and image classification. In this paper, we compare several typical theoretical TEM signal of geoelectric stratigraphy and their time-frequency distribution image respectively so as to recognize several typical signals by means of image classification. A new technique based...
