Sonar array laying method and system

Abstract

The invention discloses a sonar array laying method and system. The method comprises a step 1 of connecting a sonar array with an optical cable, and placing the sonar array connected with the optical cable on the bottom of a water area by a laying mechanism, a step 2 of the laying mechanism moving forward while laying the optical cable, and a step 3 of the laying mechanism starting an attendant state after arriving at an assigned position. The system comprises a laying mechanism and an optical cable, wherein a fiber joint at one end of the optical cable is carried by the laying mechanism, and a fiber joint at the other end of the optical cable is connected with the sonar array. The rapid sonar array laying problem in practical application is well solved, remote separate operation of a sonar array data collection system and a signal processing system is achieved, interference from surrounding support platform noise on collection equipment is reduced, the signal to noise ratio is raised, influences of support platform jitter on the collection equipment are reduced, and the working range of the sonar array is expanded.

Description

technical field [0001] The invention relates to the technical field of underwater sonar array deployment, more specifically, a method and system for deploying a sonar array. Background technique [0002] At present, radio communication and underwater acoustic communication are mainly used for ship-borne and submerged buoy communication. Among them, the attenuation of radio increases with the increase of frequency underwater. Without the help of external sensors such as towed antennas and buoys, ship-borne and submersible buoys can use ultra-long-wave and very-long-wave signals, so that ship-borne and submersible buoys can operate at depths exceeding 100 Receive communication signals from the shore to ship-borne and submerged buoys when the depth of the sea is 25 to 30 meters or submerged 25 to 30 meters. However, there are many problems in underwater acoustic communication, such as large delay, limited bandwidth, high bit error rate, high energy consumption, etc. [0003] ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems of slow speed and poor anti-interference ability in the existing sonar array deployment method, the present invention discloses a sonar array deployment method and system, which realizes the rapid deployment of the sonar array , sonar array data acquisition system and signal processing system are separated to work at a long distance; the present invention enables shore-based or ship-borne staff to know in real time the original data and acquisition nodes picked up by the sonar array data acquisition system in the case of a long distance At the same time, it reduces the interference of the acquisition equipment by the noise of the nearby support platform, improves the signal-to-noise ratio of the acquisition data, and can also reduce the impact of the support platform jitter on the acquisition equipment, and also expands the working range of the sonar array, such as shore, island Inter-chain, etc., protecting the original target detection ability of the sonar array
