Her er forklaring iflg FAS.org (den amerikanske motsatsen til Forsvarets Forsknings Institutt)
The Horizon system (Helicoptre d'Observation Radar et d'Investigation sur Zone) consists of the AS 532UL Cougar and a ground station. The Cougar helicopter operates behind the front line at an altitude of up to 4000 meters to survey the battlefield with the Thomson-CSF Target radar. This X-band radar with a swivelling antenna below the rear fuselage has a range resolution of approximately 40 meters and a target velocity accuracy of +/- seven km/h. In snapshot mode the radar can scan 20000 sq km in ten seconds. Horizon is able to survey the movements of up to 4000 wheeled or tracked vehicles at distances of up to 200 km. The French Army procured a total of four helicopters and two ground stations, which were delivered in 1996 and 1997. This represented a major reduction from the original 1980s plan in which 20 aircraft were to be procured uner the Orchidée program, which was canceled after the first flight of the fully equipped prototype in 1990. Following test missions during the Gulf War, the program was reactivated on a reduced scale in 1993.
