Research And Development Of The Geomagnetic Signal Data Field Visualization Platform

With the advent of more sophisticated geomagnetic field measuring instruments, a large number of commercial exploitation of magnetic exploration data processing software in the field of geology and mineral exploration has played an increasingly significant role. People inspired by above cases tried to use these instruments and software directly to search and detect for the magnetic targets buried in the ground in the fields of city geophysical exploration, and military dangerous goods detection, and the people got some successful experience, but researchers also found some issues about geological exploration software used in the analysis of a small underground magnetic body magnetic anomaly data such as insufficient accuracy, false alarm rate, adaptability, and poor visualization.Geological exploration involves in a wide range of fields and the targets are large and irregular, so the exploration need mass data sampling, at the same time, low accuracy requirements of the target positioning. This paper studies the magnetic exploration of positive and inverse theory applied to the specific target magnetic anomaly analysis and interpretation, and focus on improving the visualization of the data processing results.This paper apply the basic principles and common methods of a magnetic anomaly inversion and do inverse calculation based on the basic model established by the particular magnetic body, and then get the3-D coordinates of the magnetic body center and the formulas of the characteristic geometric parameters. This paper collect experimental data in professional testing ground in the use of Geomagnetic measuring instrument, and then get the inversion results and visual image by MATLAB simulation calculation. Finally, this paper uses the method of MATLAB and Visual C#mixed programming to develop geomagnetic signal data visualization platform, and verify the feasibility of the project.
