One of this method is to produce an acoustic beam with a controlled direction. 用相控声源的主要目的之一是产生一个可以控制其方向的声束.
The experimental results showed that along with increasing the delay-tirne of impulsive signal on adjacent array elements,the steered radiation angle of acoustic beam of phased-array becomes larger and larger. 实验结果表明,随着相邻阵元的激励信号延迟时间的增加,相控线阵的辐射声束指向角不断变大;
