ABSTRACT:
Data recorded by directing a single sonar beam pulse towards a surface, and recording the reflected sonar signals with a large plurality of detectors, is used to generate a mathematical representation of the surface. The mathematical representation of the surface is chosen to fit the recorded data according to a criterion such as a least squares fit of a plane to the recorded data points. A mathematical representation of on object is built up from a number of non-overlapping mathematical objects such as triangles, each triangle joined to adjoining triangles to form a continuous surface in three dimensions. Images of such mathematical representations are then presented to the observer.
