FIELD: hydroacoustics. SUBSTANCE: proposed antenna has multiconductor cable connected to N piezoelectric converters whose outputs are connected to N preamplifiers, and also test-signal generator connected to inputs of N piezoelectric converters of underwater acoustic antenna. The latter has in addition N electric equivalents, each of them being made in the form of nonpolarized component of piezoelectric converter; each preamplifier uses differential amplifier circuit arrangement whose noninverting input is connected to piezoelectric converter and inverting one, to electric equivalent. Piezoelectric converters, electric equivalents, and preamplifiers are integrated into plug-in modules; unified seats are built in multiconductor cable for connecting plug-in modules to them. EFFECT: facilitated monitoring and adjusting of antenna on its installation site. 1 dwg
