ABSTRACT:
A satellite surveillance system for providing an independent warning of attacking vehicles is realized by means of a light source detecting system that identifies discrete non-stellar light sources, locates their coordinate positions and monitors their intensity changes to determine vehicle time of arrival. All discrete light sources that exceed a given intensity level within the field of view of interest are detected and recorded in a computer memory. A catalog of stellar light sources of that intensity level and greater within the field of view is recorded in a second computer memory. The data in the computer memories are correlated by a micro-processor to distinguish between stellar and non-stellar sources. In a preferred embodiment, light source detection and monitoring is accomplished by means of a Digicon tube in combination with an array of charged coupled device detector elements.
