Rutter sigma S6 Small Target Detection/Surveillance System

The sigma S6 Small Target Detection/Surveillance (STS) has proven itself in a wide range of marine applications including Search and Rescue, marine security, lost container detection, wildlife monitoring, and scouting for ice. 

High Definition Imaging in Both Open Water and in Ice

High resolution image processing provides high definition ice imaging, leading to superior detection and tracking.  The sigma S6 user-interface provides adjustments to radar tuning to further customize the on-screen image. Following are two images, one a regular radar image, the other showing the high definition display of the Rutter system.

Track Multiple Targetssmall target

Rutter’s advanced target tracker can monitor and track hundreds of targets simultaneously, ensuring the operator has complete awareness of all activity within range.


Enhanced Ability to detect small targets at longer ranges

The sigma S6 Small Target Detection/Surveillance system improves resolution by up to 500 times over standard radars, giving it the ability to detect small targets in the water at a much greater range. The two following tables compare the ability to detect .25 sq. m and .5 sq. m. targets before processing by the Rutter system, and after. The differences are dramatic and significant, especially if the target in the water is a person or small fiberglass boat.

AIS Overlay with Class A and B Targets

Class A and B AIS target overlay options are available with full information, radar tracks and target association display.  The addition of Class B targets enables the monitoring of transponders attached to ice threats and the verification of smaller vessels operating in the area.

Multiple Client Options

The sigma S6 remote client feature allows numerous remote clients to view the master system.  The sigma S6 SeaBridge option is a low bandwidth solution facilitating information sharing between a remote radar location and multiple networked clients viewing the Ice NavigatorTM display.

Dedicated Radar Systems

Rutter can supply a dedicated high performance radar to support small target detection functionality without impacting navigational requirements. The sigma S6 STS system connects to a Rutter Radar-100S6 in a master configuration and gives the operator full control over the radar.

Camera Integration

Integration and control of IR cameras is facilitated through Rutter's sigma S6 SeaView interface.  Features include the ability to support multiple cameras, intelligent selection of a best camera for specific targets, and automatic slewing to ice targets entering a guard zone. These features support quick decision making in addressing potential threats and possible interruptions to operations.

Monitor Slow and Fast Moving Targetssmall target 1

Rutter's Dual Mode Tracker option permits the simultaneous tracking of slow moving targets as well as fast moving and maneuvering targets.

Practical and Versatile Solutions

Rutter sigma S6 technology connects to most commercially available marine radars, enabling customers to extract additional value and effectiveness from their existing radars. Should it be required, Rutter provides the option of supplying a dedicated high performance radar as an input sensor.
