Abstract
The invention discloses a towed array sonar system. The system comprises an underwater system, an on-board system and a data wet end interface module, wherein the underwater system comprises a plurality of paths of hydrophones and a plurality of digital packets; each digital packet comprises an acqusition board and a transmission board; each acqusition board is used for amplifying, filtering and sampling an acquired signal output by the correspondingly arranged hydrophone and then transmitting to the transmission board; the multiple transmission boards are used for transmitting data to the data wet end interface module in a cascading manner; the data wet end interface module is used for transmitting the data to a data recording hardware system through an optical fiber. The system has the advantages that the data can be synchronously acquired and transmitted and the data is effectively and accurately received by the system.
Description
Technical field
The present invention relates to Sonar system, particularly relate to towed array Sonar system.
Background technology
The mode classification of Sonar system has a variety of.
Can be divided into dual-use according to application type.Army uses, and sonar is mainly used in detective and instead scouts, in Underwater Target Detection and military navigation; On civilian, sonar technology can be used for understanding, detecting and use water resource.
Sonar system can be divided into initiatively and passive two kinds according to principle of work.
The sonar that sound wave is launched in autotelic active from system is called active sonar [2].May be used for the detection of Submerged moving body, and its kinematicchain element can be obtained, as distance, speed, direction etc.It not only can detect moving target, also can detect seabed pattern and various barrier, as the remains etc. of submarine, aircraft or steamer.In general, communication sonar, Echo Sounding Device etc. belong to active sonar.
The sonar that the noise or signal utilizing receiving transducer basic matrix receiving target self to send carrys out the detection of a target is called passive sonar.Passive sonar can only be passive Received signal strength, can not initiatively radiative acoustic wave, so passive sonar has hidden not easily by the feature discovered.
Typical Sonar system comprises towed array sonar, shipboard battle array sonar, double/multiple base sonar, topography and geomorphology detection sonar, Small object Imaging sonar, synthetic aperture sonar and communication sonar etc. at present.
The main following components composition of towed array sonar.
1, linear array: be made up of several nautical receiving sets, nautical receiving set is placed on towing cable inside according to fixing spacing.Nautical receiving set is transducer sound pressure signal being converted to light signal, electric signal or other signals.The length of towing cable can reach a few km, free adjustment according to demand.
2, towing cable extension and retraction system: for the folding and unfolding of towing cable and the control of towing cable attitude, comprise electric winch, aquatic bird etc.
3, signal processing system: the core system being towed array sonar, the signal received for the treatment of nautical receiving set also exchanges information with other system, also can comprise the control of the information such as temperature humidity power-supply system in towing cable cabin.
The current existing ocean sonar technology of China is in the elementary step of research, lacks the ocean sonar detection system with practicality.
