Abstract: The ahead looking sonar with 60° sector projected by multielement cylindrical array and analog beamforming technique used multielement linear array for selecting 4° x 15 beams is presented. The aim of this paper is to study the pattern directivity of the linear multielement receiving transducer of the sonar SHL-1OOM for application to electronically steered beam projector. This paper presents the result of the computer aided calculations of the beam patterns as the function of the weighting excitation parameters and damaged elements for steered linear array.
