Abstract.  We consider the method of local positioning of underwater vehicles by a hydroacoustic system with chirp probing signals. The method is based on the measurement of the distance to the object and calculating the angles at which the echo signals arrive at two or more separately placed antennas. To increase power and noise immunity, we apply linear frequency modulated (chirp) signals. We have experimentally shown the possibility of the practical use of this method for high-precision measurement of the spatial position of an underwater towed or autonomous vehicle relative to a surface vessel and, accordingly, the possibility of geo-referencing acoustic images and profilograms of the seabed obtained by the underwater vehicle. The article presents the results of the field tests of an experimental positioning system.

Key words: sonar systems, interferometric side-scan sonar, local positioning systems.
