Abstract
Ein Nachführsystem (1) zur Ausrichtung einer Reflektorantenne (2) auf eine elektromagnetische Strahlungsquelle (3) weist einen Reflektor (4) und einen dem Reflektor vorgelagerten rotierbaren Subreflektor (5) auf, der von dem Reflektor reflektierte Strahlung (12) der elektromagnetischen Strahlungsquelle (3) auf ein Empfangselement (7) lenkt und Trigger-Signale für eine Signalmessung der reflektierten Strahlung erzeugt. Der Subreflektor (5) ist gegenüber dem Reflektor (4) um einen Offset-Winkel (10) geneigt. Der Reflektor (4) ist als Abschnitt eines Paraboloids ausgebildet. Der Subreflektor kann flach, konvex, parabolisch oder hyperbolisch ausgebildet sein. Zwischen Subreflektor und Empfangselement ist ein die Strahlung führendes Führungsrohr (13) angeordnet. Das verfahren zum Ausrichten einer verschwenkbaren Reflektorantenne (2) sieht vor, daß die vom Subreflektor (5) reflektierte Strahlung (12) infolge einer Neigung des Subreflektors (5) gegenüber dem Reflektor (4) bei Rotation des Subreflektors (5) auf einer vorgegebenen Bahn ausgelenkt wird. Bei einer Fehlstellung des Reflektors (4) wird die Signalstärke der vom Subreflektor (5) reflektierten Strahlung (12) abgeschwächt und bei einer Verringerung der Fehlstellung erhöht. A tracking system (1) for aligning a reflector antenna (2) with an electromagnetic radiation source (3) has a reflector (4) and a rotatable subreflector (5) in front of the reflector, which reflects radiation (12) from the electromagnetic radiation source () reflected by the reflector. 3) directs to a receiving element (7) and generates trigger signals for a signal measurement of the reflected radiation. The sub-reflector (5) is inclined relative to the reflector (4) by an offset angle (10). The reflector (4) is designed as a section of a paraboloid. The subreflector can be flat, convex, parabolic or hyperbolic. A guide tube (13) guiding the radiation is arranged between the sub-reflector and the receiving element. The method for aligning a pivotable reflector antenna (2) provides that the radiation (12) reflected by the subreflector (5) due to an inclination of the subreflector (5) relative to the reflector (4) when the subreflector (5) rotates on a predetermined path is deflected. If the reflector (4) is incorrectly positioned, the signal strength of the radiation (12) reflected by the subreflector (5) is weakened and increased when the incorrect position is reduced.
