Share: LASAR 5

Coastal Surveillance Sonar

The C-Scope USP System is an integrated underwater surveillance and protection system based on KONGSBERG’s long experience as a supplier of maritime surveillance systems. The C-Scope USP System integrates a wide range of high-performance active and passive surveillance sensors covering the underwater domain from inner harbor to open sea. 

The C-Scope USP System performs automatic detection, tracking, classification and identification of multiple targets, and the system is designed for 24/7 operation with a minimum number of staff. 

The LASAR 5 is a part of the C-Scope family of underwater sensor portfolio. The LASAR5 is optimized for long range surveillance in coastal waters and employs active and passive mode capabilities for detection of underwater objects such as swimmer delivery vehicles and submarines. 

Overlapping LASAR5 sonars can be configured to operate in bi-static mode. High performance in demanding environments is achieved through the wide bandwidth and advanced processing techniques.

THE LASAR 5 COASTAL SURVEILLANCE SONAR 

The low frequency and the wide bandwidth provide unmatched detection and classification ranges in littoral and reverberation-limited environments, giving the needed time for decision making with inspection and reaction. 

The LASAR 5 exceptional detection ranges resulting in fewer sonars needed to cover a given underwater area. This also means reducing installation complexity and cost. Another benefit from the long detection ranges is that the sonars can be located at convenient locations (locations suitable for maintenance, locations not in conflict with fishing activities, dredging, etc) and still providing full coverage. 

Signal Processor and Operatior Workstation 

LASAR 5 is designed for multi-sensor network integration using KONGSBERG’s MSI System for signal processing and system operation. Standard Ethernet protocol is used for integration with external systems.
