Abstract
Techniques are disclosed for systems and methods to provide reliable and relatively quick bottom reacquisition in sonar systems for mobile structures, including three dimensional (3D) capable and/or multichannel sonar systems. A sonar system includes a sonar transducer and associated processing and control electronics and optionally orientation and/or position sensors disposed substantially within the housing of a sonar transducer assembly. A logic device of the sonar system is configured to detect bottom lock loss based, at least in part, on sonar data provided by the sonar transducer, determine an expected bottom depth associated with the detected bottom lock loss, and generate updated sonar data based, at least in part, on the expected bottom depth. 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.
