The invention relates to a waterborne sound generator (44) for providing a transmission signal (34) for a sonar. The waterborne sound generator has the following features: - a first signal feed (62) and a second signal feed, each of which is designed to provide an applied transmission signal (34); - a first input transformer (70), the secondary side of which is connected to the primary side of a first output transformer (72) by means of a first transmission section (66) in order to transmit the first transmission signal (36) from the first input transformer (70) to the first output transformer (72); - a second input transformer (70), the secondary side of which is connected to the primary side of a second output transformer (72) by means of a second transmission section (66) in order to transmit the second transmission signal (34) from the second input transformer (70) to the second output transformer (72); - a third signal feed which is designed to provide an applied transmission signal (34) and feed the transmission signal to a central tap of the first input transformer on the secondary side in order to couple the transmission signal (34) of the third signal feed (62) into the first transmission section (66); and - a third output transformer (72) which is designed to obtain the transmission signal (34) of the third signal feed (62) from a primary-side central tap of the first output transformer in order to feed the transmission signal to a first primary-side contact of the third output transformer.

The invention relates to an underwater vehicle with a Doppler-based navigation support system (22). The Doppler-based navigation support system has the following features: - a plurality of waterborne sound transducers which are arranged two-dimensionally or three-dimensionally and each of which is designed to convert waterborne sound into an electric signal that corresponds to the acoustic pressure and an applied electric voltage into waterborne sound; - a sound transmission unit (26) which is designed to supply a respective transmission signal (34) or a respective sequence of transmission signals (34) to each of the waterborne sound transducers (24) of the plurality of waterborne sound transducers such that at least four resulting directed transmission signals (36) are produced, wherein the resulting transmission signals (36) are directed towards the bed (38) of the body of water in a main usage orientation of the waterborne sound transducers (24) such that for each resulting transmission signal (24), a reflection point (40) is produced on the bed (38) of the body of water, and all of the reflection points (40) of the resulting transmission signals on the bed of the body of water (38) define a surface (42); - a sound receiving unit (28) which is designed to scan output signals of the waterborne sound transducers (24) in order to obtain reflections of the resulting transmission signals; and - a signal processing unit (30) which is designed to determine navigation information on the basis of the reflections of the resulting transmission signal. The navigation support system is arranged on the underwater vehicle such that the reflection points (40) are arranged such that the minimum distance between two adjacent reflection points, measured in the width direction of the surface (44), is greater than 25%, in particular preferably 50% or particularly 75%, of the quotient of the width of the surface (44) and the number of resulting transmission signals minus one resulting transmission signal.
