摘要： An acoustic transducer 1 has a first cylindrical portion 1A and a second hemispherical portion 1B on which a plurality of transducer elements 10a, 10b are arranged. The transducer elements on the cylindrical portion are arranged to have six nearest neighbors. The arrangement may be such that the six transducer elements surrounding a given element describe the vertices of a regular hexagon. The hexagons thus described may be aligned so that two of their sides are parallel to the axis of the cylinder. The elements on the hemispherical portion may be arranged so that some elements have five nearest neighbors and others have six (the neighboring elements describing, for example, the vertices of hexagons and pentagons respectively). An underwater sounding apparatus may be constructed using the transducer.

摘要： Signals entered from receiving transducer elements of 160 channels are multiplexed into 10 signal lines by 10 multiplexers. Each of 10 A/D converters converts the signals of 16 channels from analog from into digital form. The multiplexers are switched with synchronized switching timing to produce 10 pieces of sample data strings with the same timing. 160 pieces of sample data sampled in a steplike form are shifted in phase according to an oblique-line sampling scheme. The signal of the same channel is sampled twice with a phase delay of 90° so that the signal can be converted into complex-valued sample data without increasing the number of processing circuits.

摘要： The present invention is directed to provide an underwater detection system which can determine frequency components contained in echoes arriving from all azimuthal directions at high speed and enhance target discriminating capabilities by presenting such frequency components.The underwater detection system rotates a pair of ultrasonic receiving beams having a fixed phase angle difference, measures phase differences between two signals picked up by both ultrasonic receiving beams, determines carrier frequencies contained in target echoes from the phase differences, derives magnitudes and directions of moving velocities of targets from the carrier frequencies, and displays such target data in different colors. Furthermore, it provides such information as over-the-ground velocities of targets themselves upon compensating target velocity data with ship velocity data.

摘要： While keeping a propeller located in a negative direction of a y-axis turning, transmission of acoustic waves from vibrating elements of a transducer unit is interrupted. Reference signals “A” and “B” which are receiving beam signals having principal acoustic axes oriented in a propeller direction are generated from received signals obtained by “A” and “B” group vibrating elements, respectively. Next, adjustment factors used for removing propeller noise from received signals obtained by vibrating elements on positive and negative sides of an x-axis are calculated by performing arithmetic operation on time-series data on the received signals obtained by the positive and negative sides vibrating elements and on time-series data on the reference signals “A” and “B”, respectively. When performing underwater sounding operation by transmitting acoustic waves, a product of the reference signal “A” or “B” and the adjustment factor is subtracted from the received signal obtained by each of the positive and negative sides vibrating elements, respectively.

摘要： An underwater sounding apparatus includes a transducer transmitting an acoustic sounding beam along a plurality of directional surfaces that intersect in three-dimensions and receiving echoes returning from within a fish school using receiving beams. The transducer can form the receiving beams in directions generally along a substantially vertical planar directional surface and in directions generally along a substantially umbrella-shaped directional surface formed around the ship, the umbrella-shaped directional surface intersecting both a horizontal plane and the vertical, planar directional surface. A signal processing section calculates fish quantity information about the fish school by constructing pseudo-three-dimensional data from data obtained by the receiving beam. Also, the signal processing section may binarize the data obtained by the receiving beams and calculates an approximate value of the volume of the fish school by constructing pseudo-three-dimensional data from the binarized data.

摘要： An acoustic transducer has an upper cylindrical portion and a lower hemispherical portion on which a plurality of transducer elements are arranged. The transducer elements on the cylindrical portion are arranged in such a way that six transducer elements adjacent to any one of the transducer elements are located at vertices of a regular hexagon and regular hexagons adjoining in a horizontal direction have sides which are oriented parallel to an axial direction (vertical direction) of the cylindrical portion. The transducer elements on the hemispherical portion are arranged at vertices of spherical triangles constituting each of spherical pentagons obtained by projecting regular pentagons together forming one half of a regular dodecahedron onto a hemispherical surface of the hemispherical portion in which the half of the regular dodecahedron is inscribed, as well as at equal division points taken on individual sides of each of the spherical triangles and at the centers of gravity of small spherical triangles formed at intersections of parallel arcs joining the equal division points of each of the spherical triangles.
