Detection method based on bottom-sinking integrated detector

Abstract

The invention discloses a bottom-sinking acoustic-electromagnetic integrated detection device. The bottom-sinking acoustic-electromagnetic integrated detection device comprises a shell structure, wherein the shell structure is provided with a central instrument cabin; a power management module, a lithium battery, a data acquisition and processing unit, a communication module, a three-component fluxgate sensor and an attitude sensor are configured inside the central instrument cabin; a top end sensor support structure is positioned on the upper part of the central instrument cabin; a hydrophone, a pressure sensor and an electrode are arranged on the top end sensor support structure; the electrode is positioned directly above the plane circumference center of the top end sensor support structure; three supporting arms are arranged at the bottom of the central instrument cabin, and used for supporting the detection device on the bottom surface; each supporting arm is equipped with an electrode; the three electrodes are positioned on the same plane, and evenly distributed according to the circumference; and adjacent two electrodes are arranged at 120-degree intervals. The bottom-sinking acoustic-electromagnetic integrated detection device can simultaneously collect acoustic and electromagnetic signals from the bottom of water and output the acoustic and electromagnetic signals after correction. The detection speed is high, and the signal processing is fast and accurate.

Description

technical field [0001] The present invention relates to a detection method based on a sinking integrated detection device, and more specifically relates to an integrated measurement device for extracting acoustic, electrical and magnetic characteristics of underwater targets and realizing comprehensive positioning of targets. Background technique [0002] my country's marine three-dimensional detection means are scarce, and an effective comprehensive network for underwater detection has not yet been formed. Problems such as insufficient space coverage, large blind area, and high false alarm rate cannot meet the increasingly severe security needs. Especially for underwater targets, due to the lower level of physical field characteristics, the underwater propagation law is still unclear, and the background of underwater detection waters is complex, there are many interference sources, and the time-varying characteristics are obvious, which further increases the difficulty of ta...

Problems solved by technology

[0002] my country's marine three-dimensional detection means are scarce, and an effective comprehensive network for underwater detection has not yet been formed. Problems such as insufficient space coverage, large blind area, and high false alarm rate cannot meet the increasingly severe security needs.

Especially for underwater targets, due to the lower level of physical field characteristics, the underwater propagation law is still unclear, and the background of underwater detection waters is complex, there are many interference sources, and the time-varying characteristics are obvious, which further increases the difficulty of target detection. It is becoming more and more difficult for detection methods to effectively detect and find underwater targets
