Abstract : S EVERAL Air Force surveillance satellite systems designed to detect missiles by measurement of infrared radiations are currently in advanced developmental or planning stages. Before the design of these systems can be completed and transition to an operational phase begun, additional measurements must be made of the infrared background radiance levels and of the fluctuations in these levels that cause false target indications. Two simple experiments are described which will be made to bridge the gap in the required knowledge. The first experiment is designed to provide information on background intensity, dynamic range, and possible correlations in four spectral bands. The second experiment is designed to determine th general statistical nature of the background radiance in 2.7 micron band and, in particular, to determine whether or not it makes sense to discuss its Wiener spectrum.
