In partnership with the Centre for Ship Signature Management, DRDC developed a prototype signature management system (SMS) for real-time monitoring and management of ship signatures under the COSIMAR project. Using a network of onboard sensors and signature models, the system estimates the ship’s acoustic, magnetic, electric, infrared, radar, and pressure signatures, estimates the vulnerability of the platform to a library of threats, and makes suggestions to manage or reduce signatures. This international project was conducted with the Netherlands, Germany, and Norway and was completed in September 2017. To offset the loss of CFAV Quest (the expected demonstration platform), DRDC created SCORSim, a real-time simulator which replaces the ship and its onboard sensors to provide the necessary data streams to any signature management system. The entire simulation is run within the DRDC-developed SigMa Lab (Signature Management Laboratory) and is nominally a “free-play” simulation with the capability of placing and navigating the ship anywhere in the world under a wide variety of environmental conditions. Ship machinery can be operated, and ship states may be varied and the results reflected in the changing signatures and vulnerability. While established for a particular ship and SMS, the simulation can be modified for any naval platform and could also be used to evaluate potential future signature management systems.
