    • 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 sonar systems for mobile structures. A sonar system includes a sonar transducer assembly including a sonar transducer, a sonar receiver configured to receive acoustic returns from the sonar transducer and convert the acoustic returns into arrays of time differentiated sonar data samples, and a logic device adapted to communicate with the sonar receiver. The logic device is configured to receive the arrays of the time differentiated sonar data samples from the sonar receiver and process the received arrays to enhance the time differentiated sonar data samples substantially without enhancing sonar artifacts in the time differentiated sonar data samples Processed sonar data and/or resulting imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the sonar transducer assembly and/or a mobile structure.

    • Techniques are disclosed for systems and methods to provide accurate and reliable compact sonar systems for mobile structures. A sonar system includes multiple sensor channels, each comprising a sonar transmitter and a sonar receiver, and a logic device configured to provide control signals and receive sensor signals from the sensor channels. The logic device is configured to provide transmission signals to sonar transducer assemblies, where signal patterns of the transmission signals are differentiated based at least in part on frequency content. Acoustic returns are processed using the signal patterns to reduce inter-channel pickup between the sensor channels. Resulting sonar data and/or imagery may be displayed to a user and/or used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.
