Variable Depth Sonar

CVDS-26

 

Applications

• Anti Submarine Warfare (ASW) in shallow waters with extreme environmental conditions
• Mine Detection in shallow waters with extreme environmental conditions

 

To overcome the difficulty of hunting or listening for submarines that take advantage of hiding in shadow zones, a variable depth sonar is often used. The CVDS-26 is a variable depth sonar designed for active or passive operation in either omni or operator selectable sector mode. It is designed to detect, classify, and localize submarines at safe stand-off distances. The transducer array, digital transceiver and various sensors are integrated into a towed body with electronic and display consoles on-board the ship. The towed body is depth rated to 300 metres.

Features:

• OMNI ® mode operation with operator selectable Sector Mode (providing increase transmit source level)
• Transmit Beam Stabilization (TDC method)
• Electronic Receive Beam Stabilization (compensate for ship motion)
• Transmit Pulse Envelope shaping
• Electronic Multi Pulse Transmit Pulse Generation
• Electronic Calibration Mode
• Time Varied Gain (TVG) Control
• Narrow Vertical Beams
• Narrow Horizontal Beams BITE
