Scientific paper
A description is presented of a processor which is designed to detect satellites when their reflected sunlight is imaged by a continuously scanning optical telescope onto electrooptical imagers. The satellite image is unresolved and appears as a star against the night sky, except for its motion. This motion is used as a criterion for recognizing a satellite. The processor is designed to detect satellites which have a low SNR, of the order of 3, at the processor input. The implementation of the satellite detection processor using a parallel architecture, and several line comparison, allows satellites to be detected while the telescope is scanning the sky at 1096 arc sec/sec.
