Abstract

It is difficult and expensive to evaluate with radar equipment the resolution required in order that a given target be detectable. In an effort to obtain this information more cheaply and easily, an optical simulator has been constructed in which the very high resolution in an optical aerial photograph has been degraded by known amounts. Portions of typical degraded photographs are included.
