Deep sea underwater target monitoring device and monitoring method

Abstract

The invention belongs to the deep sea underwater target monitoring field and relates to a deep sea underwater target monitoring device and monitoring method. According to the deep sea underwater target monitoring device and monitoring method of the invention, alternating current capable of exciting seawater proton precession is generated in a transmitting coil, so that hydrogen protons in seawatercan transit to a high energy level; after a period of time, the emission current is turned off, the high-energy hydrogen protons gradually return to a low-energy state, and a large number of energy quanta with a Larmor frequency are released; magnetic resonance attenuation signals are induced in a receiving coil; and an underwater target is determined according to the features of received abnormal signals; the signal features of the monitoring device are obtained in real time through a data processing center established on the land; and after analysis and processing are performed, the parameters such as position, size, heading and speed of the underwater target are given. According to the deep sea underwater target monitoring device and monitoring method of the invention, the magnetic resonance technology is applied to deep sea underwater target monitoring, so that the deep sea underwater target monitoring device and monitoring method have the advantages of larger monitoring range, higher sensitivity, high accuracy of acquired information and the like compared with the prior art. With the deep sea underwater target monitoring device and monitoring method adopted, effective means of deep sea underwater target recognition and monitoring are expanded.

Description

technical field [0001] The invention relates to the field of deep sea underwater target monitoring, in particular to a deep sea underwater target monitoring device and a monitoring method. Background technique [0002] The long-term monitoring and precise identification of underwater targets is one of the research hotspots in the field of modern national defense and ocean engineering. In recent years, the strategic position of the ocean has become more and more important, and human monitoring activities on the ocean are increasing. Accurate positioning and identification of underwater targets has become one of the important topics in the field of ocean engineering. In terms of military affairs, the monitoring of targets such as submarines and underwater gliders has always been a key issue in maritime defense. Including the inland sea, territorial sea, exclusive economic zone, etc., we have about 3 million square kilometers of "blue territory". It is of great significance to...
