Abstract

An Infra-Red Target Generator (IRTG) has been developed to generate a scene whereby the motion and IR signature of an aircraft and countermeasures may be simulated. This scene is presented to a missile seeker head in a surface-to-air or an air-to-air engagement. The opto-mechnical design required the mixing of two IR beams representing aircraft and countermeasures in the 1-5 um spectral band. Both sources may be modulated in intensity and time with a series of rotary neutral density filters and shutters. The focal plane components also allow for variation of source angular size.
