Large Area IR Scene Projector
Infrared scene generators are used in Hardware-in-the-loop (HWIL) ground test facilities to test functional capabilities of complex and expensive seeker systems and to reduce the risk associated with expensive flight tests. New countermeasures are being developed against air-to-air (AA) and surface-to-air missiles (SAMs), especially man-portable air defense systems (MANPADS), to keep aircrews safe in urban and close-support battlespaces. For both applications, the evaluation of critical performance parameters of algorithms, optics, and sensors relies on the ability to generate extended infrared images that approximate typical targets, countermeasures and backgrounds.
Current IR scene projectors are limited in size (2”x2”) and total output power, using 1024 x 1024 arrays of 50 μm square pixels. This necessitates expensive optics to enlarge these images to simulate real targets. ICX Photonics
has demonstrated small arrays of 0.25 and 0.5 inch pixels. We are working toward modules of 64 x 64 pixels which could be tiled together to make arbitrarily large, even wall-sized arrays which can accurately simulate real targets without expensive IR projectICX Photonics
for seeker HWIL testing.
