Visible-to-IR-Transducer-Based Infrared Image Projection Systems

摘要

DGA/DCE/LRBA (Laboratoire de Recherches Balistiques et Aerodynamiques), the French MoD missiles and navigation evaluation center has develoepd several HWIL facilities in order to test the IR-autoguidance-loops of tactical missiles. This IR autoguidance laboratory is composed of several IR image projection systems based on a visible to IR transduction principle. A previous paper has presented the 1999 achievements of LRBA in this field of research. This new paper first describes the latest evolutions achieved by LRBA in this domain, and then details the image projection layouts based on these improvements. It consists in two main facilities : a ground target scene projection layout and a much more complex animated air target scene projection system. This second testbed features the simultaneous use of a low temperature scene projection layout and three high temperature channels designed to modelize the hot parts of an aircraft and its environment. This alows the delivery of continuous images (100percent fill factor) for anti-aircraft missile evaluation, at a relatively low cost. The optimization of this facility and especially the channels synchronization and spatial superposition is also discussed.
