首先简要回顾一些线阵列和可导向阵列的基础知识。1点声源的相互影响双声源在垂直平面上它们相距1/2波长,声波相互抵消上下的输出指向性。在水平平面上,是声源矢量相加之和,总输出如图1所示。
Let’s briefly review some of the basics of line arrays and steerable arrays. Interaction of 1-point sound sources The two sound sources are 1/2 wavelength apart in the vertical plane and sound waves cancel each other up and down in output directivity. In the horizontal plane, is the sum of the sound source vectors, the total output shown in Figure 1.
