Abstract
A radar system for active obstacle warning and imaging of the surface of the earth, working in the pulse frequency or FH-CW range, which can be used in on-line operation in real time, includes 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. 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.

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.
