Military application of staring infrared focal plane subassembly

With the development of military technology, the level of demand, to infrared detector in the field of scout, control and guide, is more and more high. Now, infrared detector has attained Ⅲ generation——infrared focal plane arrays. In this paper, the conception of staring infrared focal plane arrays is discussed, as well its advantages of military application, comparing with the mechanical scanning system, for example, improving heat sensitivity and SNR , compact structure of detector, and a batch of production, easy to process signals. According to the situation about SFPA of each wavelength, some advices about how to use current technology to develop this system are given.
