The threat of infrared homing missiles against ships is significant because of low cost, high performance imaging seekers and the striking contrast of the ship and its contours against the ocean background. NATO Navy’s need this information to assess susceptibility to these threats. Additionally, the threat of asymmetric threats to ships such as highly manoeuvrable small water craft has increased significantly in recent years.


Task Group Number 79/SET-144 (TG51), titled “Mitigation of Ship Electro-Optical Susceptibility against Conventional and Asymmetric Threats,” which ended on 31 December 2012 focused on: infrared modeling of military ships, shipborne Infrared Search and Track systems (IRST) and their detection of point targets in a marine environment, IR signature/detectability of small craft, evaluation of IR ship signature monitoring and management systems and infrared modelling challenges unique to the littoral environment. This charter takes full advantage of the progress made by SET-144 and extends it in several areas of interest to many NATO Navies. The main purposes of the new Task Group will be as follows: (a) cooperative field measurement programs to validate ongoing modeling and simulation efforts of radiometric signatures of maritime targets, both large combatants and smaller special operations craft (b) assessments of the detection capabilities of shipboard IRST and other infrared sensors against airborne low altitude point sources and small surface targets against land backgrounds; (c) research on infrared ship signature management systems, closely cooperating with the follow-on group to SET-154 and SET-166 and (d) research on impact of IR signature on ship susceptibility, closely cooperating with SCI-224


- Research IR signature management systems - Research into ship signature features not previously studies, such as wakes, radar systems. - Develop techniques to model the infrared properties of IR ship decoys - Continue essential research into environmental effects - Extend signature research of small craft by emphasizing new threat bands and shift focus from detection to identification.
