The present invention is directed to a transducer module including a two-piece protective assembly offering mechanical protection for one or more transducer elements (i.e., transmitter(s) and/or receiver(s)) provided within. The two-piece protective assembly comprises an internal rigid housing including a cavity formed by a set of walls or projections extending from a rear portion thereof. The cavity is shaped and/or sized to receive the one or more transducer elements within. The two-piece protective assembly further includes a cover overmolded and coupled to the rigid housing and sealing the one or more transducer elements within the cavity of the housing.

Machine learning algorithms can interpret three-dimensional sonar data to provide more precise and accurate determination of seafloor depths and in-water target detection and classification. The models apply architectures for interpreting volumetric data to three-dimensional forward-looking sonar data. A baseline set of training data is generated using traditional image and signal processing techniques, and used to train and evaluate a machine learning model, which is further improved by additional inputs to improve both seafloor and in-water target detection.

Abrégé

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.

A 3-dimensional sonar system having a fixed frame of reference including a transmitter and receiver array. The system may include a single ping processor for processing received echoes from a single transmission including methods to match filter sonar sensor data, to optionally compensate for self Doppler, beamform sonar sensor data, to extract bottom targets from beamformed data and to extract in-water targets from the beamformed data. The system may also include a multi ping processor to operate on the outputs of multiple pings from the single ping processor including methods to detect tracks from in-water targets.
