Abstract
A sonar system for arctic seafloor reconnaissance has a pair of transducers affixed to a holder so as to form a transducer array. A vertically extended tube assembly rotatably supported by a tripod suspends this transducer array at a specified depth in water such that the transducer array is tilted at a specified tilting angle and oriented in a specified azimuthal direction. One of the transducers is made to emit directional acoustic signals and the reflected acoustic signals received by both of the transducers are converted into electrical signals. These signals are processed together with signals indicative of the tilting angle and the orientation of the transducer array to obtain seafloor imagery and depth data.
