Infrared focal plane array (FPA) technology has advanced rapidly in the past two years. This technology promises advantages for future PLIR systems as well as advanced missile concepts. RCA has been in the forefront of this technology and has pioneered an IR focal plane array based upon Schottky Barrier detectors. This paper describes the technology and its status. Following a short description of the technology, the background of its development will be presented, and then a more detailed description of the device will be provided, including some performance measurements of the device.
