摘要： Example steering control systems and methods for multiple devices are provided herein. A system includes a trolling motor assembly (120) having a propulsion motor and a steering actuator and a sonar assembly (130) comprising a transducer assembly and a directional actuator. The system further includes a user input assembly that is configured to detect user activity related to controlling operation of the trolling motor assembly and operation of the sonar assembly. The system further includes a processor that is configured to determine a direction of turn based on user activity, generate an electrical turning input signal indicating the direction of turn, and direct either one or both of the steering actuator and the directional actuator, via the turning input signal, to adjust a direction of either one or both of the propulsion motor and the transducer assembly accordingly.

摘要： A system is provided for imaging an underwater environment. The system includes two 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 create arcs of sonar coverage extending forward from a watercraft, from each side of the watercraft, and downward of the watercraft. Accordingly, multiple 2D live sonar images can be formed. One or more of the multiple sonar return beams can be selected and used to form sonar images that anglers are used to, without requiring separate transducer elements.
