Abstract
During the joint Canada–France minehunting trial in Brest Harbour, France, in June 2004, a sidescan sonar survey at multiple look angles was conducted over a Rockan–shaped target. In the absence of physical verification of the orientation of the target on the seabed, it has been attempted to determine this by constructing a very simple model of how it would appear in processed sonar imagery depending on the look angle and parameters such as sonar range and altitude. The model results have been compared with the real sonar data collected during the trial and an estimate of the orientation of the Rockan target is made. Though the model is entirely lacking in physics, the results are surprisingly good at minimal computational cost. A tool such as this could be useful in interpreting what is seen in sidescan sonar imagery of Rockan targets, for example which surfaces produce highlights.
