Abstract

Bei einer Unterwasserantenne mit mindestens einer Wandlerreihe (11) aus einer Mehrzahl von hintereinander gereihten, voneinander beabstandeten, elektroakustischen Wandlern (12) und mit einem in Schalleinfallsrichtung (10) hinter der Wandlerreihe (11) angeordneten Reflektor (13), der mindestens eine schallharte Reflektorplatte (16) mit einer den Wandlern (12) zugekehrten, ebenen Vorderwand (161) und einer von den Wandlern (12) abgekehrten Rückwand (162) aufweist, ist zur Unterdrückung von sich im Reflektor (13) in Richtung der Längserstreckung des Reflektors (13) ausbreitenden Moden die Rückwand (162) von der Reflektorplatte (16) so gestaltet, dass der Abstand (a) der Rückwand (162) von der Vorderwand (161) über die längs der Wandlerreihe (11) gesehene Länge des Reflektors (13) variiert.
