DGA/DCE/LRBA, the French MoD missiles and navigation evaluation center has developed several HWIL facilities in order to test the IR-autoguidance-loops of tactical missiles. LRBA has initiated the acquisition of SPECTRAL, a dedicated hardware and software configuration. SPECTRAL (Multipurpose System for Laboratory Evaluation of Image Processing Calculators) is a complete system including hardware and software designed for the evaluation of different missile functions or equipment (on-board image processing software, image processing calculators, imagers, terminal guidance and control performances). The main feature of this system is its capability to generate images representative of those elaborated by an infrared missile seeker, in real time. SPECTRAL is designed with an architecture for a multi-user environment including workstations carrying out several operations. Acceptance Test Procedures of SPECTRAL are being discussed and the first results are presented here. As a conclusion, we provide a comparison with existing image generating systems at LRBA's facilities.
DGA/DCE/LRBA (Lab. de Recherches Balistiques et Aerodynamiques), the French MoD missiles and navigation evaluation center has developed 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. In this paper, we present all the improvements and new acquisitions taking place this coming year in our HWIL facilities.
DGA/DCE/LRBA (Laboratoire de Recherches Balistiques et Aerodynamiques), the French MoD missiles and navigation evaluation center has developed 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 allows the delivery of continuous images (100% 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. As a conclusion, future HWIL facilities are presented.
