Abstract
A system is for recognizing obstructions and monitoring movements on or above an airport area (1) with sensors (2, 3, 4). A sensor (2) is a radar device having a plurality of antenna elements (12, 14), which are affixed to a curved surface (15) of an antenna carrier (2a) and are turned on, one after the other, in terms of time. Thus a first part of the antenna elements (14) is disposed on a first circular line (13) on the surface of the antenna carrier (2a), and a second part of the antenna elements (12) is disposed on a circular line (15) perpendicular to the first circular line (13). Therefore the data of the radar device (2) are evaluated in a first ROSAR process, to image the situation on the ground, and in a second ROSAR process, to image the heights of the flying objects to be observed.
