Description

Technical Field

[0001] The present invention relates to the field of sonar detection, and in particular to an active and passive variable depth sonar system, which is mainly used for underwater target detection and acoustic intelligence collection. Background Art

[0002] As submarine noise becomes smaller and smaller, it is increasingly difficult for traditional surface ships to effectively detect the movements of submarines with passive towed array sonars, and they are increasingly at a disadvantage in future naval battles. Active and passive sonars integrate active and passive sonars. Because active sonars emit sound waves that are reflected by obstacles, they can change the current situation where submarines cannot be detected due to their ultra-low noise or silent state. At present, most of the main active and passive sonars are separated, with double capstans and deployed separately. Their main drawback is that they are inconvenient to retract and use. During use, there is a risk of entanglement between the active sonar and passive array cables. Summary of the invention

[0012] Furthermore, in order to facilitate the sliding of the transmitting array module onto the supporting plate module, a guide wheel is installed on the supporting plate module.

[0013] Furthermore, in order to facilitate the sliding of the transmitting array module onto the pulley support plate, the pulley is installed with a hydraulic telescopic rod, which can control the pulley support plate to tilt below the water surface.

[0014] Furthermore, in order to control the straightness of the external passive sonar, the transmitting array module is rear-mounted to utilize the fluid resistance of the transmitting array module.

[0015] Furthermore, in order to prevent the external passive sonar from being interfered with, the external passive sonar adopts an optical fiber array.
