Abstract:
The invention relates to a method for the destruction of a localized mine, wherein an unmanned underwater vessel cooperates as a primary vessel (11) with another unmanned remote-controlled underwater vessel acting as a secondary vessel (12) and which is provided with an explosive charge for explosion purposes. In order to reduce clearing costs in comparison with a method which uses a disposable vessel and in order to reduce clearing times in comparison with a method using a re-useable clearing vehicle, the primary and secondary vessel (11,12) are used in an autonomously operating tandem mode, wherein the secondary vessel (12) is remote-controlled by the primary vessel (11). The tandem mode is effected as far as the mine (33) from the primary vessel (11) outwards by means of stored positional data on the localized mine (33) and on-board assisted navigation data; the mine (33) is relocalized by means of acoustic and/or optical sensors and the secondary vessel (12) is positioned in relation to the the mine in a remote-controlled manner once the mine has been relocalized and the explosive charge is exploded by remote control.
Abstract:
The invention relates to a mine hunting system and a mine hunting method. For effective, time-saving minesweeping, which is carried out under cover, a fleet of autonomous submarine vehicles are used. A first vehicle group consists of reconnaissance vehicles (12), each equipped with mine-detection sensors (14) and a second vehicle group consists of engagement vehicles (13), each equipped with a mine destruction charge (17).
Abstract:
Bei einem Verfahren zum Prüfen der Zerstörung einer mittels einer Sprengladung (20) gesprengten Seemine (13) werden zur zeitsparenden und zuverlässigen Feststellung der Zerstörung der Seemine (13) die bei der Sprengung ausgelösten Druckwellen mittels eines im Seegebiet minenfern platzierten Empfängers (21) als Empfangssignal aufgefasst. Das Empfangssignal wird auf das Auftreten von Detonationsereignissen innerhalb eines Zeitfensters untersucht und das Vorhandensein von zwei Detonationsereignissen als Minenzerstörung angezeigt (Fig. 2).
Abstract:
The invention relates to an electroacoustic converter for using under water, said converter comprising a reflector (11) and a hydrophone (12), especially a ceramic hollow sphere, which is axially distanced from the reflector and is arranged upstream of the reflector (11) in the sound incidence direction. The aim of the invention is to obtain a flat phase course without phase shifts, even after a flush integration into the outer skin of a boat body. To this end, a reflector ring (16) which is concentric with the hydrophone (12) is arranged upstream of the reflector (11), the inner annular wall (161) of the reflector ring being at a radial distance from the hydrophone (12). The spatial association of the hydrophone (12) and the reflector ring (16) is such that the hydrophone (12) is arranged at a pre-determined distance (h) from the front surface (162) of the reflector ring (16), opposing the reflector (11). The hydrophone can at least partially project past the front surface or be set back from the front surface (162) of the reflector ring (16).
Abstract:
The invention relates to a test method for a process used for passively obtaining target data of a moving target that radiates wave energy, particularly sound. According to said method, bearing angles are measured as real target data by taking the bearing of the target by means of an on-board bearing system at successive path positions of a vehicle, particularly a watercraft that determines the path positions thereof with the aid of a compound navigation system, and the distance, speed, course, and/or position of the target are determined therefrom as additional real target data. In order to be able to quickly verify the serviceability of said TMA method on line in a sea acceptance test, the positions of the target and the vehicle are measured using a GPS at the moments in time the bearings of the target are taken. The bearing angle and the distances of the target are calculated from the respectively associated positions of the vehicle and the target and are allocated to the path positions that are measured using compound navigation. A reference target path is estimated therefrom as well as from the associated pairs of values of the bearing angle and the distance of the target by means of estimation filters, and reference target data is derived therefrom so as to be directly compared to the real target data.

Abstract:
The invention relates to a method for generating a three-dimensional terrain model while using object-oriented vector data that contain supporting points, which describe the terrain, of position values indicating at least the their cartographic position, and of elevation values that indicate their height or depth with regard to a reference level. The aim of the invention is to obtain a stable method that automatically ensues without human interaction. To this end, the elevation values of the supporting points are extrapolated within a uniform grid, and all extrapolation values are subjected to a weighted interpolation.
