Abstract

This paper describes work performed by the DERA Farnborough UK to provide a laboratory based simulation capability for investigating airborne Infra Red Countermeasure performance against both current reticle threat seekers and future seekers incorporating focal plane array imaging technology. The object of the work was to provide a hardware in the loop facility based around a Five Axis Motion Simulator (FAMS) built by Carco, to allow tests and flyout simulations to be undertaken for performance evaluation. The principal area of research involved the design and construction of a number of source rigs for fitting to the target, or outer, arm of the FAMS to allow both aircraft and countermeasure sources to move realistically in relation to a seeker mounted on the inner FAMS axes. Rigs that have been built include, a multiple point source rig capable of allowing aircraft and multiple countermeasure point sources to move independent of each other, a wide band source rig incorporating a multiple wavelength refractive collimator for investigating spectral countermeasures and two color seeker technology and a rig based on a two port collimator which allows optical mixing of high temperature countermeasure sources.
