    摘要: A transducer assembly comprises a housing and a plurality of frequency steered transducer array elements. Each of the transducer array elements includes a plurality of piezoelectric elements. The frequency steered transducer array elements are configured to receive a transmit electronic signal including a plurality of frequency components and to transmit an array of sonar beams into a body of water. Each sonar beam is transmitted in an angular direction that varies according to one of the frequency components of the transmit electronic signal. The frequency steered transducer array elements are positioned within the housing in a fan-shaped configuration where an end section of at least two of the frequency steered transducer array elements are within an intersection range of each other.

    摘要: A marine docking and awareness system for facilitating docking and otherwise maneuvering vessels in marine environments. A navigation system may include a plurality of directional cameras and an image processing computer. Each directional camera generates images of the marine environment in a particular direction. The image processor processes the images from the cameras, including enhancing the images in accordance with various features. The features may include identifying and highlighting water and/or objects, adding distance markers, predicting and warning of collisions with objects, defining and adding virtual boundaries around the vessel and warning when an object crosses a boundary, automatically selecting the most relevant cameras based on the direction of movement or on an object crossing a boundary, combining multiple images from different cameras into an image, and displaying desired, projected, and historical tracks.
