Developments in Modelling the Use of Infrared Offboard Countermeasures in an Infrared Anti-Ship Missile Scenario.
Abstract
This work deals with the evolution of a FORTRAN simulation written by Naval Research Laboratory which is used to evaluate the effectiveness of deploying ship launched infrared decoys to counter the anti-ship infrared seeking missile threat. Although the model (referred to as the Stochastic Infrared Engagement Model - SIREM) possesses extensive analytical capability and flexibility, refinements are desired to more accurately emulate atmospheric effects on the acquisition process. In this thesis, methods are derived to calculate atmopsheric transmittance as a function of range using an accurate, LOWTRAN-based empirical formula. Basic seeker discrimination techniques are addressed which may be incorporated into SIREM to other simulations for future missile-versus-decoy evaluations; and some ideas are presented which may prove valuable in decoy enhancement to subjugate the discriminating seeker. Keywords: Offboard countermeasures; Infrared seekers; Infrared countermeasures; Computer coding; Atmospheric transmittance.
