An apparatus for providing marine information is provided including a user interface, a processor, and a memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to generate a sonar image based on sonar return data received from an underwater environment, determine a location associated with the sonar return data based on location data received from one or more position sensors, and render a nautical chart on a display. The computer program code is further configured to cause the apparatus to receive a user input on the user interface directed to a portion of the display in which the nautical chart is presented, and modify presentation of the nautical chart such that the portion of the display presents the sonar image in response to receiving the user input.

A data processing apparatus is provided, which includes processing circuitry. The processing circuitry is configured to acquire a data set from target detected by a detection apparatus, perform rendering of the data set, and generate a plurality of views arranged on a screen. Each view of the plurality of views includes a plurality of pixels. Each pixel included in the plurality of views is associated with a plurality of pieces of information including a first information displayed on the screen and a second information that indicates a view among the plurality of views to which the pixel belongs.

A computing device is configured to receive a plurality of sets of sonar data, current locations associated with the sonar data, and condition parameters associated with the plurality of sets of sonar data from one or more marine electronic devices. The computing device receives a request from a user to display a condition and location based fishing activity s report. The request indicating a location and a condition parameter associated with desired fishing activity. The computing device filters the plurality of sets of the sonar data based on the request to generate a fishing activity report including one or more portions of the plurality of sets of the sonar data that are associated with the indicated location and the condition parameter and causes display of the fishing activity report on a screen such that the one or more portions of the plurality of sets of the sonar data are displayed.

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.

Sonar devices for detecting underwater objects are provided whereby a set of angled ultrasound transducers are employed to sense ultrasound signals from a plurality of different spatial regions. The angled ultrasound transducers may include a first pair of side-viewing ultrasound transducers and a second pair of ultrasound transducers configured for interrogating forward and reverse directions. The ultrasound signals from the set of angled ultrasound transducers may be processed to identify the presence of underwater objects in each spatial region, and the resulting identified underwater objects may be displayed, on a per-region basis, on a user interface. The ultrasound signals may additionally or alternatively be processed to generate a topographical model of the bed surface, and to generate a topographical surface image based on the three-dimensional topographical model. The topographical surface image may be displayed as a fly-over animation.

Techniques are disclosed for systems and methods to provide accurate and intuitive control over the display of sonar image data provided by sonar systems for mobile structures. A sonar system includes a user interface and a logic device configured to receive and display multiple different sonar image data sets from multiple different types of transducer modules to a user. The logic device is configured to render a historical view selector on a display of the user interface, where the historical view selector is configured to provide for selection of a particular view time in a period of time corresponding to the first and/or second sonar image data, receive user input identifying a selected view time within the range of time, and render first and second portions of the first and second image data corresponding to the selected view time on the display of the user interface.
