摘要：the invention includes a sonar transducer of an even number of stacked lineararray antennas are identical.the core is driven by a reciprocating rotary motion of smallamplitude (e.g., 9, 10 branches, transmitting and receiving antennas are in halftransmittingantennas and receiving antennas are mutually staggered with an angle equal to the angleof rotation of the set.all antennas are different from the receptrices all transmittingantennas at an angle equal to the phase delay of the emission lobe is compared with thereception lobet.
