Hull Mounted Sonar
The CTS/CMAS family of Hull Mounted Omni® Sonar systems answers the world Navies' requirements for advanced, compact, ship mounted Sonar systems for use in Surveillance, ASW, MCM and other support roles in coastal waters.
CTS/CMAS Sonar systems are designed to the highest quality and reliability standards. Innovative concepts combined with advanced technology provide features and functions required for both small and large ship installations.
CTS-24
Applications
- ASW operations in deep and shallow coastal waters.
- Shallow and deep water anti-submarine warfare
- Mine detection/avoidance (surface, moored and bottom mines)
- Mine countermeasures
- ROV/AUV tracking
- General surveillance
The CTS-24 is a medium-frequency (24 kHz) omni sonar designed for navies operating in shallow as well as deep water. The narrow beams maintain excellent performance in shallow water, while the operating frequency provides extended detection ranges in deep water. It integrates the hull mounted transducer with a digital transceiver to provide simultaneous active and passive digital signal processing, display processing and computer-aided target detection and tracking using CW or FM modulation.
Features:
- Lower frequency operation with standard CMAS-36/39 sonar features
- Compact design for new or existing vessel installations

CMAS-36/39
Applications
- Coastal patrol
- Navigation aid / obstacle avoidance.
- Search and recovery of bottom targets
- Mine countermeasures
- ROV/AUV tracking
- General surveillance
The CMAS-36/39 (36 – 39 kHz) is designed as a multipurpose hull mounted sonar for shallow water surveillance applications. The multibeam sonar uses narrow horizontal and vertical receiving beams as well as high-speed scanning and digital processing techniques to provide instantaneous detection, classification and target data through a full 360° field of view. Sector transmission is operator selectable in 24° sectors for operation in areas such as harbours or narrow channels.
Features:
- OMNI® mode operation provides for instantaneous detection, and tracking of targets in a full 360º field of view.
- Sector mode for versatility in harbour and channel patrol.
- Narrow vertical and horizontal beams - ideal for shallow water operation.
- Electronic Tilt/Electronic Stabilization for optimum target detection capability in the water column or on the sea bottom.
- Automatic target detection and automatic target tracking; information on ship's track, and target track, range, depth, bearing, speed and heading available instantaneously for multiple targets.
- High Resolution MCM mode with zoom
- Interface to integrated command/ control center (C3 System and Display Console)
- CW and FM chirp.
