Paper Abstract

Current interest in space based interceptors using IR sensors to home on and intercept ICBM's during early phases of flight make earth background scene generation in the opaque, infrared bands between 3.0 - 15.0 (μm) an important issue. This paper describes an approach for generating scenes in these opaque regions for arbitrary geometry and spatial resolution from measured data of fixed geometry and limited spatial resolution. Power spectral densities (PSD's) in the appropriate regions are constructed from various measured sources and used to synthesize images for a specific geometry by fractal continuation. This approach is particularly useful since it avoids the severe computational complexity and time penalty involved with a first principles approach. This is especially important for generating the large number of scenes required for ground testing high frame rate KEW sensors. An evaluation of the sensitivity of a typical acquisition algorithm to the accuracy of the background PSD's used to generate the synthetic scenes is also presented.
