Problems solved by technology

Take the PRB M409 anti-personnel mines produced in Belgium as an example. These mines have a diameter of 8.5 cm and a metal content of only 1 gram, which makes them much harder to detect than conventional mines with metal covers (metal mines)

Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0060] Implementation example 1:

[0061] Such as figure 1 , 2 As shown, the present invention is mainly used in the field of compound mine detection target detection. Using the scheme of GPR combined with EMI signals can greatly improve the precise detection of low metal mines, reduce the false alarm probability of metal mine detectors for metal impurities, and use linear The predictive approach reduces the effects of measurement systems, background fields, and noise in GPR signals. The core content...

Abstract

The invention provides a method and system for composite mine detection target detection, and the method comprises the steps: 1, determining the position of a metal target according to an electromagnetic induction EMI mine detector, and obtaining a suspected target; and 2, judging whether the suspected target is a landmine or not according to the GPR signal. According to the invention, accurate detection of the low metal thunder is completed by combining the EMI signal and the GPR signal, and the false alarm probability of the metal thunder detector to a metal target is reduced; a linear prediction technology is used for replacing a traditional detection mode of directly using target signal intensity to resist clutter intensity, the influence of a measurement system, a background field andnoise in a ground penetrating radar signal is greatly reduced, and the signal to clutter-to-noise ratio of the ground penetrating radar signal is enhanced.

Description

technical field [0001] The present invention relates to the technical field of composite mine detection, in particular to a method and system for detecting a composite mine detection target. In particular, it relates to a composite mine detection method based on electromagnetic induction EMI and ground penetrating radar GPR. Background technique [0002] The two most widely used mine detection instruments that exist today are metal detectors and ground penetrating radar. Metal detectors are based on the difference in electrical conductivity and magnetic permeability between soil and metal targets, and use the metal parts of the mine as the detection object of electromagnetic waves. The low-frequency electromagnetic induction mine detection technology is simple and effective, and is more suitable for individual operations. It is also used in vehicle-mounted mine detection systems. However, due to the fact that there are usually a large number of fragments after the explosio...
