Two methods of the beam patterns shaping for multielement linear transducers in nearfield are know. In the first method of shaping the beam in the near field can be narrowed by shortening the transducer and weighting, but the beam is not sufficiently well formed. The beam in the near field can also be formed by shifting the signals from the particular elements for focusing of the receiving beam. Selected beam patters for focused and beamformed (steered) are presented. The paper presents approach to beamformer in the nearfield.
