Abstract. The article describes the results of testing and practical application of small-sized multifunction sonar system with a chirp sounding signals developed in the Kotel'nikov Institute of Radio-engineering and Electronics of Russian Academy of Sciences, Fryazino branch. Multi-channel digital sonar system includes an interferometric side-scan sonar, high-frequency echo sounder and low-frequency profiler with common controller and registration program, providing simultaneous registration, both the signal and navigation data. Multifunction hydroacoustic systems were tested in two variants, differing in the frequency range of interferometric side-scan sonar - 250 kHz and 70 kHz.

Key words: interferometric side-scan sonar, linear frequency modulation, remote sounding, echo sounder, profiler.
