REAL-TIME ENVIRONMENTAL SURVEILLANCE DEVICE FOR THE DETECTION AND PURSUIT OF POSSIBLE ENEMIES

摘要

A device (1) analyzes the surrounding space to periodically provide, at a sufficiently fast rate, an image in the form of a plurality of pixels. An extraction circuit (2) extracts, from among said pixels, those which satisfy a first criterion usually satisfied by any pixel representative of a possible enemy machine, and provides said processing means with information relating to pixels of the surrounding each of said extracted pixels. A processing circuit (3) processes the thus extracted pixels and their respective surroundings to determine whether they satisfy additional criteria usually met by any pixel and its surroundings, representative of a possible enemy machine, in order to decide which pixels Extracts are representative of an enemy craft.
