摘要： An underwater detection apparatus (1, 1a) is provided. The underwater detection apparatus (1, 1a) includes a transmission transducer (10, 10a, 10b), a reception transducer (5, 5a), an attitude information receiver (14), a transmission circuit (18, 18a), and a reception circuit (4, 4a). The transmission transducer (10, 10a, 10b) includes a plurality of transmission elements (A, 32) configured to be fixed to a vessel (S), each transmission element (A, 32) extending in an oblique direction relative to a fore-aft direction of the vessel (S). The reception transducer (5, 5a) includes a plurality of reception elements (B). The attitude information receiver (14) acquires an attitude information of the vessel (S). The transmission circuit (18, 18a) drives the plurality of transmission elements (A, 32) based on the attitude information to make the transmission transducer (10, 10a, 10b) transmit a transmission wave in a given direction relative to the water surface. The reception circuit (4, 4a) obtains a reception signal from each of the plurality of reception elements (B) based on a reflection wave of the transmission wave, the reflection wave being received by the reception transducer (5, 5a).

摘要： Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing mountable to a watercraft having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one sidescan transducer array in the housing that receives first and second sonar returns with first and second transducer elements and converts the first and second returns into first and second sonar return data. A sonar signal processor may then generate a 3D mesh data using the first and second sonar return data and at least a predetermined distance between the transducer elements. An associated method of using the sonar system is also provided.

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.

摘要： The measured values for depths and deposits, as measured with a fan echo sounder, are subject to errors due to the diffraction of sound in water bodies and the movement parameters of the survey vehicle. Said errors must be analysed and eliminated, by extensive measurements of the average speed of sound and of the movement of the vehicle. As a rule a region to be surveyed will be swept in tracks, in such a way that the bands surveyed by the fan echo sounder overlap. The same bed elements in an overlap region are, thus, determined more than once. Consequently, in said overlap region, differences in depth are determined, which, by means of multiple linear regression analysis are minimized, or, better, optimised. In this manner, correction factors for the mean speed of sound and for the displacement parameters pertaining to the survey vehicle are calculated. The surveying of the bed-profile of a stretch of water is improved, by use of the disclosed method and rendered independent of an online evaluation during the survey voyage.

摘要： The method for stabilizing and forming channels of a multichannel sonar comprising at least a system (3, 4) for monitoring the sea bottom fixed to a carrier (2), the system (3, 4) further comprising an emission antenna (3) insonifying a volume (5) of the sea bottom and used in near field in the Fresnel area and comprising a reception antenna (4) with variable opening and forming joined channels (i), the method comprising in order to cover the sea bottom observed by a sequence of images of quasi-joined observation areas (7) on the sea bottom, for each recurrence: in a first step (9), evaluating the displacement L(n) of the bottom observation area (7), for a current recurrence (n) as a function of the displacement and of the position of the carrier (2) with respect to the observation area (7) between the preceding emission (n-1) and the current emission E(n); in a second step (10) determining the pitch δ(n) between channels (i) for the current recurrence (n) from a preset number N of channels (i), of the displacement L(n) precedingly evaluated and the pitch δ(n-1) between channels (i) of the preceding recurrence (n-1); and in a third step (11), resetting in real time the direction of the reception axis to the direction of the emission axis of the current recurrence (n) and, from said direction, forming successively the N reception channels (i) unset and having a width δ(n) to cover the image field of the current recurrence (n). The method for stabilizing and forming channels as well as the sonar for implementing such method apply particularly to the fine monitoring of the sea bottom in anti-mine operations.
