Patent ID: 7023375

Claim:
Radar system for active obstacle warning and imaging of the surface of the earth, working in the pulse frequency or FM-CW range, which can be used in on-line operation in real time, comprising a plurality of antenna elements for sending and receiving radar signals, which are arranged on the fuselage of an aircraft, and which may be turned on and scanned sequentially, whereby a synthetic aperture can be generated by means of periodic sending and receiving of the antenna elements, wherein the antenna elements are arranged along the curved surface of the aircraft contour, whereby a SAR processor is present, which analyzes the data obtained from the antenna elements and displays them as processed radar images on board the aircraft, in a virtual cockpit; and wherein the synthetic aperture that is generated from a first predetermined segment of the antenna elements is processed according to the linear ROSAR method; and wherein the synthetic aperture that is generated from a second predetermined segment of the antenna elements is processed according to the linear SAR method.
