FIELD: physics.
SUBSTANCE: in order to obtain seismoacoustic information in 3D format with minimal technical, time and economic costs and eliminate noise reflections during acoustic probing of bottom sediments, the invention proposes to install a linearly extended seismoacoustic antenna at the bottom of the water body and tow a pulse emitter at a certain distance from said antenna perpendicular to the line of the position thereof. While towing, coordinates of the point of emission and time of emission are recorded for each pulsed signal emission and signals emitted by the towed pulse audio source are detected using a special receiving hydrophone mounted at the bottom linearly extended seismoacoustic antenna in a single time scale over the entire towing time.
EFFECT: obtaining an acoustic image of an environment in 3D format by forming resolution on three coordinates, range and two angles.
