Sector-scanning sonars are finding increasing use in a number of undersea scenarios. These sonars perform rapid scanning of a given sector by a vertical fan-beam having narrow horizontal beamwidth.1 The range resolution of these sonars is on the order of a few centimetres, with maximum ranges of a few hundred metres depending on the frequency of operation (100 kHz — 2 MHz).2 This paper presents results on 3D reconstruction of objects from their acoustic images. The acoustic images used in this paper are obtained by simulation using a high-resolution imaging sonar model. We also present some results on object classification.
