School geometry measurements using a sonar accuracy and an algorithm for school detection
Original version
This report is not to be cited without prior reference to the authorAbstract
The accuracy of geometric measurements of schools, using horizontal guided single-beam or
multi-beam sonar, is simulated. For both types of sonars, the accuracy is dependent of
horizontal beam-width and range. As multiple beams do not overlap, the accuracy for multibeam
sonars increases with school size. An algorithm for numeric detection, area measurements,
and classification of schools are outlined.
