Abstract:
A method of tracking a target moving in an airspace,wherein a search space is searched with the aid of a search sensor in multiple passes in a first clock rate (2&pgr;/&Dgr;T1) and target information being established in this way which describes a track flown through by the target, an expected flight path is extrapolated with the aid of calculation means from the target information established from at least two passes, and flight path data, which describes the expected flight path, is provided for a tracking sensor, which covers a tracking space, the flight path data, which describes the extrapolated expected flight path, is transmitted to the tracking sensor with the aid of transmission means at a second clock rate (2&pgr;/&Dgr;T2), which is higher than the first clock rate (2&pgr;/&Dgr;T1), and when the target reaches the tracking space, the tracking sensor is aimed at the expected flight path with the aid of aiming means on the basis of the transmitted flight path data, independently of the detectability of the target, the target is detected with the aid of detection means as soon as it is detectable by the tracking sensor, and the tracking sensor is tracked on the target autonomously with the aid of tracking means.
