Embodiment Construction

[0040] The purpose of the present invention is to use vehicle-mounted detection to enhance the anti-interference ability to various complex climates or environments, improve detection accuracy, and then use multi-arrays to increase detection speed, and use the combination of feature database and inversion method to improve processing speed and achieve Explain the precision requirements. First, explain the technical terms mentioned in the invention:

[0041] Numerical simulation response characteristic database: a database that uses theoretical models for numerical simulation calculations.

[0042] Measured response characteristic database: a database established by collecting data in the laboratory or in a work area with known conditions before detection, and then obtaining a large amount of data through the actual physical model, which contains the same parameters as the physical quantity and numerical simulation response characteristic database .

[0043] Iterative inversi...

Abstract

The invention discloses a vehicle-mounted array detection method and system based on feature inversion. The method includes: Step 1: Perform the first detection in the working area to obtain the precise measurement area and the first detection response. The precise measurement area Included in the working area; Step 2: Conduct a second probe in the precise measurement area obtained in Step 1 to obtain the second probe response; Step 3: According to the first probe response obtained in Step 1 and the second probe response obtained in Step 2 Carry out iterative inversion, and output the center point position, inclination and inclination of the target body after the iteration is completed; the system uses vehicle-mounted detection to enhance the anti-interference ability against various complex climates or environments, and improve detection accuracy; use multiple arrays to improve detection Speed; In terms of processing and interpretation, the combination of feature database and inversion method is used to improve processing speed and meet the requirements of interpretation accuracy.

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...
