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 PASAR 1250 is a part of the C-Scope family of underwater sensor portfolio. The PASAR 1250 is optimized for open sea surveillance in order to cover the outer coastal surveillance zone typically beyond range of active sonars.

The PASAR 1250 employs passive mode capabilities for detection of underwater objects such as swimmer delivery vehicles and submarines. High performance in demanding environments is achieved through the long array aperture and advanced processing techniques.

THE PASAR 1250 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.

Modular acoustic array sections provides the flexibility to adapt the sonar configuration to different lengths and performance needed.

The PASAR 1250 exceptional detection ranges resulting in fewer sonars needed to cover a given underwater area. This also means reducing installation complexity and cost.

Signal Processor and Operatior Workstation

PASAR 1250 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.
