Underwatre antenna for fitting to the hull of a submarine.

Abstract

In the case of an underwater antenna for fitting to the hull of a submarine, having a transducer arrangement (15) which, in the installed position, extends along the hull (11), extends over an area and has a reflector (21) and a multiplicity of electroacoustic transducer elements (20) which are arranged at a distance alongside one another and one above the other and are located in front of the reflector (21) in the sound incidence direction, in order to provide a flank antenna whose weight and installation volume are optimized for fitting to a submarine and has a good signal-to-noise ratio, the reflector (21) is subdivided over the entire length of the transducer arrangement (15) into reflector areas (212, 211) which are located one above the other and have a reflection behavior matched to reception frequency bands from different frequency ranges, with the reception frequency band from the highest frequency range being associated with the uppermost reflector area (212) in the installed position, and with the reception frequency band from the lowest frequency range being associated with the lowest reflector area (211) (Figure 4).
