圆锥台阵方向性系数最佳化

Study of Largest Directivity for Conical Array

首先给出计算圆锥台阵最佳方向性系数的一般过程 ,然后对一个特定的圆锥台阵进行计算机模拟。用 Ansoff HFSS软件仿真此模型 ,给出结果 ,并与均匀幅度同相激励进行比较。

This paper begins with a general formulation of calculating the largest directivity for conical array. Simulations of a special conical array are made on computer. This model is then emulated by Ansoft HFSS, and the results are given and compared with that of a uniform amplitude and cophasal excitation.
