基于声场预报的共形阵波束优化方法与实验研究

Conformal Array Beampattern Optimization Method and Experimental Research Based on Sound Field Forecast

在工程实际中,声接收基阵波束设计和优化的一个重要问题是实际阵列流形的获取。由于实际测量阵列流形的工作面临很多困难,难以推广使用,本文提出声场预报的方法,使用ANSYS和SYSNO ISE软件模拟测量阵列流形的过程,通过对复杂结构基阵的声场进行数值预报,得到了与实际相符合的基阵阵列流形,并通过共形阵水池实验验证了该方法的有效性。

In many engineering applications, the key problem in the beampattem design and optimization of sensor arrays is to obtain array manifold. However, measuring the array manifold in practice is usually very difficult, A new method based on sound field forecast is proposed, which uses softwares ANSYS and SYSNOISE to simulate the process of measuring real array manifold. Simulation result is consistent with real array manifold. Water-tank experiments with some conformal srray verifies the effectiveness of the proposed method.
