FIELD: measuring.
SUBSTANCE: invention relates to hydroacoustic signalling devices and can be used to detect a moving underwater object in an interference hydroacoustic field. Multielement interference detector of a moving underwater object further comprises in the radiation unit a two-channel power amplifier and a second radiating antenna device. Input of the two-channel power amplifier is connected in series to the generator, and the output is connected in parallel to the first radiating antenna device and the second radiating antenna device.
EFFECT: high efficiency of the interference detector under conditions of non-stationary and non-uniform reflecting properties of the sea surface.
