Abstract
The invention relates to a submarine antenna to be attached to the hull of a submarine, said antenna comprising a planar converter arrangement (15) which extends along the hull (11) when attached and which has a reflector (21) and a plurality of electroacoustic converter elements (20). Said converter elements are arranged next to and interspaced from each other and are arranged in front of the reflector (21) in the sound incidence direction. The aim of the invention is to optimize said lateral antenna for attachment to the submarine in terms of its weight and volume and signal-to-disturbance ratio. According to the invention, the reflector (21) is subdivided across the entire length of the converter arrangement (15) into reflector zones (212, 211) that lie one beneath the other and that have a reflection behavior tuned to receive frequency bands of different frequency ranges, the receive frequency band from the highest frequency range being associated with the top reflector zone (212) when attached and the receive frequency band from the lowest frequency range being associated with the bottom reflector zone (211).
