Harbour 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 40-360 is a part of the C-Scope family of underwater sensor portfolio. The LASAR 40-360 is optimized for surveillance in challenging harbor areas which need protection of specific assets. The LASAR40-360 employs active and passive mode capabilities for detection of underwater objects such as divers and small underwater vehicles. The sonar head can be deployed in several configurations including seabed mounting, jetty wall mounting and over the side deployment.

THE LASAR 40-360 HARBOUR 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. 

Separate transmit and receive acoustic arrays provides the flexibility to adapt the sonar configuration to different environmental conditions and specific harbor constraints. 

The LASAR 40-360 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 40-360 is designed for multi-sensor network integration using KONGSBERG’s MSI System for signal processing and system operation, yet LASAR 40-360 as a single sonar configuration can be run from a rugged Workstation. Standard Ethernet protocol is used for integration with external systems.
