A detection and localization system mounted on an airborne vehicle, and which enables detection of objects having at least one face inclined relative to the surrounding flat horizontal ground and therefore presenting a contrast with this ground. A radar transceiver is connected to an antenna rotating around the airborne vehicle and has a low directivity in a pitch plane and a high directivity in a roll plane, associated with a generator of distance cells. Making use of mathematical relations, an on-board computer, knowing the altitude of the airborne vehicle and the roll angle of the emitted radar wave, localizes the inclined face which produces a much higher reflection of the emitted radar wave than the surrounding ground, to thereby detect the inclined face.
A Procedure for detecting and localizing objects surrounded by a substantially flat surface and having at least one substantially flat face inclined at an angle of more than about 10.degree. with respect to the substantially flat surface, by an airborne vehicle over-flying the substantially flat surface, comprising the steps of:
