STRUCTURALLY-INTEGRATED, SPACE-FED PHASED ARRAY ANTENNA SYSTEM FOR USE ON AN AIRCRAFT |
摘要 |
A phased array antenna system for an aircraft which allows a beam from the antenna to be scanned down to or below the horizon when the aircraft is traveling at high latitudes. The system comprises a conformal phased array antenna aperture mounted on either a top, port or a starboard side of a fuselage of the aircraft, and at least one feedhorn mounted either in a blade secured to the fuselage or in a leading edge of a horizontal stabilizer of the aircraft. The feedhorn illuminates the conformal antenna aperture and the aperture projects a beam therefrom which can be more easily directed at targets at or below the horizon. The invention allows smaller antenna apertures to be used to scan a beam toward the horizon. |
