SUBAQUEOUS TERRAIN MODELLING - AN AID TO SCANNED SONAR IMAGE INTERPRETATION

In the relatively shallow areas of coastal and sheltered waters, the echo returns from seabed features frequently dominate the data received by sonar systems. During the development of sector scanning sonars at Loughborough University the need to provide some additional information as an aid to the interpretation of the received echo structure was identified. The Civil Engineering Department at the University had been investigating computer imaging techniques in the modelling of terrain surfaces likely to be modified by the impact of engineering operations, and had developed a predictive ground model. The natural extension of this work into underwater survey was therefore of interest to both research groups.
