The application of mosaic focal planes to the problem of satellite surveillance has resulted in an increased interest in background clutter. Perhaps the most stressing background, in terms of its sharp radiance gradients and the existence of edges, occurs under conditions of high solar reflection off of clouds. A high reflectance scene, simulated in two spectral bands, was used to study the clutter induced by platform drift and jitter across such a background. Clutter was studied as a function of footprint, drift rate, and RMS jitter amplitude for first and second difference filters. These results were then compared against those derived from a simulated scene representing a more typical cloud background. All results presented are for a synchronous orbit system.
