Share: LASAR 40M

Mobile 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 40M is a part of the C-Scope family of underwater sensor portfolio. The LASAR 40M is optimized for surveillance of specific areas which need temporary protection. The sonar head can be deployed in several configurations including seabed mounting, jetty wall mounting and over the side deployment. 

The LASAR 40M is well suited for fleet protection while at anchor. When naval forces participate in international operations they may have to call temporarily into forward and less secure bases bringing with them suitable systems for protection. LASAR 40M is designed with focus on easy deployment, operation and recovery.

THE LASAR 40M 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 40M 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 Operator Workstation

Rugged Workstation Laptop Computer is used for signal processing sonar operation. Standard Ethernet protocol is used for integration with external systems.
