Abstract

Durch die geringe Länge der synthetischen Apertur-Unterwasserantenne ist das Unterwasserfahrzeug in seiner Navigation bei hohen Geschwindigkeiten eingeschränkt. Die Erfindung schlägt eine Unterwasserantenne zum Empfangen von Unterwasserschallsignalen mit einer ersten Subantenne und einer zweiten Subantenne vor, wobei die erste Subantenne und die zweite Subantenne jeweils wenigstens ein Empfangselement aufweisen und die erste Subantenne und die zweite Subantenne einen Ortsabstand ausbilden. Somit können Unterwasserantennen bereitgestellt werden, welche ebenfalls über eine synthetische Apertur verfügen, jedoch bei deren Verwendung Unterwasserfahrzeuge größere Geschwindigkeiten verwenden können. Zudem können Unterwasserantennen mit defekten Empfangselementen weiter betrieben werden.
