ABSTRACT:
A sonar system has at least two separated bottom-mounted acoustic modules, each module including a projector for generating horizontal sound beam, a vertical line receive array for monostatic and bistatic detection, and a high frequency, upward-directed transducer for providing a steerable vertical beam to ensure full water column coverage by the use of surface reflections to minimize shadowing caused by high relief bottom topography.
