The geometrical fixation of the arrangement II in the area of the source field takes place on the basis of an aperture level III and comprises an aperture space IV and is task-specific or solution-specific.
Die Lösung der erfindungsgemäßen Aufgabe erfolgt weiterhin durch die Gestaltung der Anordnung II in Form einer EM-Quellfeldsynthese durch vorzugsweise planare oder dreidimensionale Strahlerelemente (VI), die vorzugsweise parallel zur Aperturebene III und IV auf einem geeigneten, vorzugsweise dielektrischen Träger (V) aufgebracht sind und in ihrer Anordnung aufgabenspezifisch verteilt sind und durch Steuerelemente bestimmter hochfrequenter Transmissionseigenschaften verbunden sind (VII) (Abb. 3). Die Anordnung der Strahlerelemente ist grundsätzlich im Bereich des Aperturraumes, welcher durch die beiden Aperturebenen eingeschlossen wird, lösungsspezifisch vorzugsweise parallel oder dreidimensional zur Aperturebene. Die Generierung des parasitären Quellfeldes im Bereich des Aperturraumes erfolgt durch eine steuerbare Wechselwirkung der Strahlerelemente mit dem Quellfeld der Quelle 1 (passiv) oder lösungsspezifisch durch Überlagerung des Quellfeldes mit verstärkender Wirkung (aktiv) bzw.

Ein besonderer Vorzug der Erfindung besteht in der Verknüpfung der Steuersignale für die Feldsteuermatrix und der zeitverknüpften Auswertung der gewonnenen Signale durch eine geeignete Anordnung von Prozessor- und Signalbehandlungskomponenten dergestalt, dass ein anwendungsspezifisches Signal gewonnen wird, welches eine ebenfalls anwendungsspezifische Aussage über die Änderung von Vektoren in Betrag und Phase (z.B. der Richtung) des empfangenen Quellfeldes zur Position der Empfangseinheit bei genauer Aussage über das Erreichen des Optimums (Vektor = 0,0) zulässt ohne dabei die Systemfunktion insgesamt zu verändern oder zu beeinträchtigen.A particular advantage of the invention is the combination of the control signals for the field control matrix and the time-linked evaluation the signals obtained by a suitable arrangement of processor and signal processing components such that an application-specific signal is obtained which also provides an application-specific statement about the change in vectors in magnitude and phase (for example the direction) of the received source field to the position of the receiving unit with a precise statement allows you to reach the optimum (vector = 0.0) without changing or impairing the overall system function.

Die Änderung der Strahlbeeinflussung wird adaptiv mit der Änderung der Nachführaufgabe vorgenommen. The change in the beam influence is made adaptively with the change in the tracking task.
