Abstract

A new method is presented for designing the wideband stagger-tuned array (WSTA) which was first put forward by Zhang et al. [Chin. J. Med. Instrum. 9(3), 5-10 (1985)]. Based on the beam-equivalence principle and the sampling-composing law, this method is simple in calculation and good in precision. An optimized array scheme and expected beam pattern can be obtained by simulating a given beam pattern. Within +/-20 degrees, the simulative error is below 1%. The experiment was conducted and the results showed excellent agreement with simulation and calculation for the major-lobe scope. (C) 1997 Acoustical Society of America.
