Background

In the last decade the use of Electro-Optical (EO)/ Infrared (IR) Seekers (EO/IR) technologies in Anti-Ship Missile (ASM) seekers and surveillance systems has greatly expanded. This presents an increased threat to NATO forces. The aim of the group is to increase the probability of ship survivability through the development of better tools to support tactics and countermeasures development against these threats. The group will accomplish this goal using all digital engagement modeling and simulation tools validated against existing sea trial data. The predecessor of the group (SET-211) has a lot of expertise in measuring and simulating ship signatures. They will also benefit from the results of the SCI-224 group on EO and IR-Countermeasures against Anti-ship Missiles.

Objectives

ET-105 will address the following topics: • Deficiencies in current modelling and measurement methods that relate to dynamic effects. o How accurately describe dynamic signature phenomenology through modeling, measurements and control system. • Existing metrics used to define signature requirements and identify shortcomings. • The connection between signature, detection range, and survivability. • Techniques to achieve certain signature levels. ET-105 will produce publications and recommendation for a Task Group to address the ET findings.

Topics

• Define methodology for establishing, verifying, and maintaining IR ship signature requirements in preparation for a STANAG; • Determine the influence of atmospheric propagation effects (Turbulence, Scintillation, Refraction, etc.); • Exploitation of Signature Reduction (ex. Washdown) and other Dynamic Signatures (including plume effects) with model validation; • Calibration and measurement in SWIR, NIR, VIS phenomenology; • Design of experiments/Environmental Sampling (how do you sample the environment space); • Summarize efforts in Plans of Work (POW) and Terms of Reference TOR in preparation to transition to a Task Group.
