Embodiment Construction

[0035] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, in the present invention, a plurality of electric field measurement electrodes and one reference electrode are arranged based on an electric field electrode array. Collect potential signals at different positions, analyze and obtain the electric field characteristic quantities at different positions to realize the detection and positioning of underwater targets.

[0037] The underwater target detection and positioning method specifically includes the following steps:

[0038] Step 1: All the electric field electrodes collect data in real time. At any sampling time, judge whether there is an abnormal value of the potential measurement of an electric field electrode greater than the detection threshold. If there is, it is judged that there is an underwater target, and perform step 2, otherwise continue to step ...

Abstract

The invention relates to an underwater target detection and positioning method based on array arrangement of electric field electrodes. According to the method, the electric field electrodes are arranged in an arc array, the electric field electrodes meeting a certain condition are combined to a detection array group, underwater target positioning parameters are respectively computed by differentdetection array groups through adopting an electric field positioning algorithm, and finally, the plurality of groups of underwater target positioning parameters are fused to obtain an accurate underwater target three-direction coordinate position and an electric dipole moment. The method is suitable for the field of underwater safety warning and has good algorithm adaptability and high positioning precision.

Description

technical field [0001] The invention relates to the technical field of underwater target detection, in particular to a method for detecting and locating the target in water by using its electric field characteristics. Background technique [0002] Underwater, it can detect and locate underwater targets through the acoustic field, electromagnetic field and optical characteristics of underwater targets, so as to realize underwater target detection. For most underwater targets, because they are made of different metals, the self-corrosion and corrosion protection system will generate electric field characteristic signals such as electrostatic field and axial frequency electric field, which can be used for detection and positioning. At present, there is still a lack of methods for locating targets in water based on electric field characteristics. Contents of the invention [0003] The purpose of the present invention is to propose a method for detecting and locating targets i...
