A study on beam optimizing of wideband stagger-tuned array

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....

description 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°, 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.
