Method and apparatus for recognizing the start and motion of objects

摘要

A recognition system for alarming and early warning against starting and approaching flying objects with an active engine evaluates the "plume signature" of such an engine. Image signal generating electro-optical sensors, which operate in a preselected spectral range, are combined with an image processing and evaluating arrangement for producing output signals that can initiate countermeasures semi-automatically or automatically after a threat analysis has established that a threat exists.
