System for frogman and underwater vehicle detection

Abstract

The invention discloses a system and a method for frogman and underwater vehicle detection. The method detects frogmen and underwater vehicles in open waters at great depth in the working mode of mounting a detecting sonar and various sensors on an underwater mooring platform of anchor mooring. The system mainly comprises the detecting sonar, a cradle head, a platform control cabinet, an acoustic beacon, a bearing composite rope, the mooring platform, a pressure sensor, a surface acoustic velocity sensor, an attitude sensor, an acoustic array, an anchor and the like, the detecting sonar is connected with the mooring platform through the cradle head, the attitude sensor, the pressure sensor and the surface acoustic velocity sensor are supplemented for data correction, the acoustic beacon is combined for real-time positioning, and the bearing composite rope of the mooring platform is controlled to ascend and descend to enable the detecting sonar to work at the set optimum depth. The system and the method are applicable to the fields of underwater security, underwater monitoring and the like.

Description

technical field [0001] The invention relates to a detection system for frogmen and underwater vehicles. Background technique [0002] After the "9.11" incident, the world's security situation has undergone profound changes. Preventing terrorist attacks and hostile forces' invasion has become the focus of military objectives. Countries have adopted various advanced technical means for air and land attacks, which has greatly improved the overall defense. Level. However, the lag in the level of underwater defense makes this area a weak spot for the whole world. [0003] According to relevant reports, some extremist terrorists once wanted to use frogmen to plant mine weapons on the passages of famous British yachts to blow up yachts; there are also terrorists who want to tie bombs to frogmen and commit suicide on board There are also terrorists using frogmen to carry small bombs to blow up warships docked in ports. All these planned activities have caused panic and unrest in ...

AI Technical Summary

Problems solved by technology

[0007] Usually, in shallow water areas, you can install sonar and various sensors on the bottom of the base, and then place the base on the bottom of the water for detection. However, when the monitoring water reaches a certain depth, various sensors cannot be used. method is not feasible, so other means are needed to solve the detection problem of underwater targets such as frogmen and underwater vehicles
