The invention relates to a launching device (101) for an unmanned submarine vehicle, in particular for an autonomous submarine vehicle or for a vehicle that is operated in a remote-controlled manner, having a launching tube (105) which has an inner wall (107) and an outlet (271), and the unmanned submarine vehicle located in the launching tube, wherein the unmanned submarine vehicle has a vehicle shell with vehicle-shell inhomogeneity (133, 135, 137, 143, 145), such that ejection of the unmanned submarine vehicle causes different contact loads between the vehicle shell and the inner wall, wherein the unmanned submarine vehicle has a detachable compensating form (160) which is configured such that the vehicle-shell inhomogeneity is compensated and so a combination (201) of the unmanned submarine vehicle and the detachable compensating form results in a substantially regular contact load between the combination and the inner wall when the combination is ejected.

In particular in the case of a side-scan sonar, large intensities with respect to the sound pressure under water are emitted in order to be able to detect objects at large distances, with the result that the reflected signal of very distant objects can be detected well. This procedure has some disadvantages. In order to be able to achieve the high sound pressure, high-performance energy sources such as batteries are necessary. In addition, (interference) signals are also reflected at the surface of the water. Furthermore, reflections of objects in the vicinity are very strong, with the result that the sensitivity of underwater microphones has to be reduced. The invention therefore relates to an underwater sound signal which has a first transit time difference and/or a first intensity difference along a first irradiation angle, wherein the first transit time difference and/or the first intensity difference are/is impressed on the underwater sound signal and this impressing process occurs, in particular, during transmission or reception.

The invention relates to a method for classifying one or more watercraft on the basis of the sound waves (2) emitted or transmitted by these craft. In this case, the sound waves (2) are received by an arrangement of waterborne sound sensors of a Sonar receiving installation (4) and processed to form received signals (6). At least one amplitude spectrum (24) is produced from these received signals (6), said amplitude spectrum (24) having one or more sets of frequency lines and possible single lines, from which characteristic craft parameters (28) are determined automatically in a frequency line pattern identification module (26) or manually. Subsequently, the characteristic craft parameters (28) are compared with parameters in a database, with this comparison being rated with a correspondence factor (34). One or more watercraft are determined as a result of the classification, taking the correspondence factor (34) into account. Furthermore, the invention relates to a corresponding device for carrying out the method.
