| 摘 要： | 根据波束等价和采样合成定理，对由若干同心圆环构成的二维非线性参差调谐宽带阵列换能器，进行波束优化计算机模拟．结果表明，给定一个期望的波束分布，通过计算机模拟运算，可获得环形参差阵的一组结构参数，其波束分布与给定的波束分布在误差范围内一致

| 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. |
