Abstract: A system is provided for imaging an underwater environment. The system includes a transducer assembly with at least one transmit transducer element and an array of receive transducer elements. Each receive transducer element is configured to receive sonar returns and form sonar return data. A sonar signal processor is configured to receive the sonar return data from each receive transducer element and generate sonar image data. The sonar return data from all of the receive transducer elements may be summed and used to form a high-definition 1D (e.g., time-based) sonar image. The sonar return data from only a subgroup may be summed and used to form a lower-definition 1D sonar image. In some systems, an array of series-connected transmit transducer elements can be used. The orientation of the emitting faces of the array may vary slightly to mimic a curved surface for increased beam coverage.

Abstract: An amplifier circuit (100) to be used in a sonar (10) is described. The amplifier circuit (100) includes a transducer (101) and a matching circuit (102). The transducer (101) has an impedance characteristic having a resonance frequency and an anti-resonance frequency higher than the resonance frequency. The matching circuit (102) is connected to the transducer (101). The impedance characteristic of the transducer (101) connected to the matching circuit (102) has a first resonance frequency and a second resonance frequency higher than the first resonance frequency.

Abstract: The invention generally relates to sonar devices that integrate forward-looking sensors with down-looking echosounders, side scanning sonar, or both. The invention provides a sonar system that includes a forward-looking sonar device that operates in an integrated fashion with one or more other sonar devices so that a boater can have a reliable navigation tool while also using sonar for finding fish and other features on the seafloor. The forward-looking sonar can include a transducer array that takes a three-dimensional acoustic reading of the objects and seafloor ahead. The electronics that process the acoustic data can also process data from down-looking sonar, side-scanning sonar, or both and can integrate the information to present an expansive display in the boat, revealing the contents and the floor of the sea in front of, around, and under the boat.

Abstract: A system is provided for imaging an underwater environment. The system includes one or more arrays of transducer elements. Each array is operated at a fixed phase shift and varies in frequency so as to beamform multiple sonar return beams of a first range of angles and a second range of angles. The arrays can be oriented to cover the gap in sonar coverage for other arrays to create a continuous arc of sonar coverage. Accordingly, a 2D live sonar image can be formed. One or more of the multiple sonar return beams facing downwardly can be selected and used to form downward sonar images that anglers are used to, without requiring separate transducer elements. Fish arches formed using multiple sonar return beams can be positioned appropriately within a high resolution downward sonar image to form a desirable combined sonar image.

Abstract: An underwater detection device (10) is provided, which includes a beam setting module (15a) and a transmission/reception controlling module (15b). The beam setting module (15a) sets, among a plurality of beams (2, 2a, 2b, 2c, 2d, 2e, 2f, 2g) set for underwater detection, a combination of beams (2, 2b, 2c, 2d, 2e, 2f, 2g) satisfying a condition for suppressing an influence of mutual interference between the beams. The transmission/reception controlling module (15b) simultaneously transmits and receives the combination of beams (2, 2b, 2c, 2d, 2e, 2f, 2g).

Abstract: A target object measuring device and a method of measuring a target object are provided, which can accurately calculate the size and/or the weight of an underwater target object by utilizing a transducer. The target object measuring device includes a transducer, a target object echo signal extracting module, a peak detecting module, a peak incoming direction calculating module, a time difference calculating module, and a target object measuring module. The transducer transmits a transmission wave underwater and receives a reflection wave. The target object echo signal extracting module extracts an echo signal indicative of a target object from data of the reflection wave. The peak detecting module detects each of a plurality of peaks included in the echo signal. The peak incoming direction calculating module calculates an incoming direction of each of the plurality of peaks based on the reflection wave. The time difference calculating module calculates a time difference between a timing of appearance of a first peak and a second peak different from the first peak, among the plurality of peaks, a difference in the incoming direction between the first peak and the second peak being smaller than a given threshold. The target object measuring module calculates data related to a size and/or a weight of the target object based on the time difference.
