Vehicle-mounted array type detection method and system based on feature inversion

Abstract

The invention discloses a vehicle-mounted array type detection method and system based on feature inversion. The method comprises the steps: 1, carrying out the first detection in a working region, obtaining an accurate measurement region and a first detection response, wherein the accurate measurement region is contained in the working region; 2, carrying out second detection in the accurate measurement area obtained in the step 1 to obtain a second detection response; 3, carrying out iterative inversion according to the first detection response obtained in the step 1 and the second detectionresponse obtained in the step 2, and outputting the center point position, inclination and inclination angle of the target body after iteration is completed. The system adopts vehicle-mounted detection, enhances the anti-interference ability to various complex climates or environments, and improves the precision in detection. The detection speed is improved by utilizing multiple arrays; in termsof processing interpretation, a feature database and an inversion method are combined to improve the processing speed and meet the requirement for interpretation precision.

Description

technical field [0001] The invention belongs to the field of geophysical transient electromagnetic methods, and in particular relates to a vehicle-mounted array detection method and system based on feature inversion. Background technique [0002] As a powerful exploration method, geophysical method has always played a very important role in the field of exploration. Among them, for metal targets, the magnetic method and the electrical method are two methods that are widely used. Magnetic prospecting is a widely used prospecting method. However, since the magnetic method uses the earth's magnetic field and is a passive source, when there are magnetic impurities in the detected area, the magnetic anomaly signal of the low-resistance target may be disturbed by other interference sources. Covering, it is difficult to judge the position of the low-resistance target body through the isomagnetic line diagram. In addition, when the geomagnetic environment is complex, the false ala...
