【Abstract】 This paper presentes a discussion that the beam of the nonlinear two dimensional wideband stagger tuned array transducer which consist of several circular elements can be optimized, and the optimizing beam simulation is made by the computer according to the beam equivalence principle and the sampling compositive law. The simulation results show that if an expected optimum beam pattern is given, a series of structure parameters can be obtained after simulation operation, and the beam pattern of the simulated array transducer coincides with the given ones.更多还原
