dc.description.abstract	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.	no_NO
