摘要： The invention relates to a bathymetric system comprising a multi-beam emitting and receiving device attached to a carrier vehicle (1), configured, in a first recurrence, to measure the amplitude of a first plurality of beams reflected off the seabed, and a computer configured to determine the three-dimensional spatial coordinates of a first scan swath (11). According to the invention, in a second recurrence, the device is configured to emit a second incident beam and to measure the amplitude of a second plurality of beams reflected off the seabed, and the computer is configured to determine the three-dimensional spatial coordinates of a second scan swath (22), so that at least one probe point of the first scan swath (11) is redundant with a probe point of the second scan swath (22), and the computer is configured to calculate an altitude variation of the carrier vehicle using altitude variations of spatial coordinates of the at least one redundant probe point (31) between the first recurrence and the second recurrence.

摘要： Sonar rendering systems and methods are described herein. One example is an apparatus that includes a transducer element, position sensing circuitry, processing circuitry, and a display device. The processing circuitry may be configured to receive raw sonar data and positioning data, convert the raw sonar data into range cell data based at least on amplitudes of the return echoes, make a location-based association between the raw sonar data and the positioning data, plot the range cell data based on respective positions derived from the positioning data and rotate the range cell data based on a direction of movement of the watercraft to generate adjusted range cell data. The processing circuitry may be further configured to convert the adjusted range cell data into sonar image data, and cause the display device to render the sonar image data with a presentation of a geographic map.

The first and second flexible circuits each include a first side, a second side, and a plurality of adhesive areas spaced apart and positioned in a line along one edge of the first side. The transducer elements each include a first surface attached to one of the adhesive areas of the first flexible circuit, an opposing second surface attached to one of the adhesive areas of the second flexible circuit, and a third surface positioned between the first and second surfaces. The transducer elements form a linear array with the third surface of each transducer element in alignment and configured to transmit and receive an acoustic pressure wave.

摘要： The invention relates to a method for measuring a ground profile by means of a transmitting arrangement for directed emission of sound signals mounted on a waterborne vehicle (2) and a receiving arrangement having at least two transformers for receiving the sound waves reflected by the ground profile. The transformers A and B each generate a received signal (24) that is sampled and saved at predetermined sampling points in time. A coarse delay time (44) is determined from the received signals (24) of two transformers, indicating the number of sampling points in time by which the received signals (24) are shifted. Using the shifted received signals (28), a phase difference Δ φ is determined for a predetermined number of sampling points in time, each corresponding to a fine delay time (52). A chain difference (56) can be determined from the sum of the coarse delay time (44) and the fine delay time (52) for said sampling points in time, from which a received angle (60) and an impingement coordinate (64) can be derived in conjunction with a signal curve time (38) of the sound signals. The invention further relates to a device for carrying out such a method.

摘要： Disclosed is an underwater antenna which operates at a large frequency band range and whose transmission and reception characteristics feature high transmission power and reception sensitivity. Said underwater antenna comprises several transducer arrays (30), each of which encompasses a plurality of electroacoustic transducers and is provided with a composite member made of composite material that is composed of piezoelectric or electrostrictive ceramic elements embedded in a polymer. Several ceramic elements are covered by one common electrode (21) on each face so as to form the electroacoustic transducers (13). In order to be able to produce the underwater antenna in a technically simple and compact manner so as to be able to use the same in small, unmanned underwater vehicles, the composite members are embodied as spatially limited sectors in a plate (26) which is made of the same composite material and is fitted with full electrode areas (19) that are disposed on the external faces of the plate and contact the ceramic elements. Furthermore, at least one full electrode area (19) is subdivided into strip-shaped electrodes (21) in the zones covering the sectors. Said strip-shaped electrodes (21) are longer than they are wide and are placed in a row at a certain gap distance (23) from each other in the direction of the strip width.

摘要： The invention relates to a method for producing a sonar image from an underwater area, wherein a sonar, which is supported by a watercraft, is used. Said sonar comprises an emitting antenna which is used to emit sound impulses and a capturing antenna which comprises a capturing sector which is used to capture sound waves scattered back from the underwater area. The sonar data obtained by scanning undergoes modified tomographic signal processing in order to obtain a high local resolution of the underwater area in the capturing area, by scanning the underwater area with a relatively small part of the capturing antenna.
