摘要
以典型的超声相控一维阵列探头为研究对象,从其声束指向性函数入手,分析了超声相控一维阵列探头的阵元中心距在消除栅瓣方面的作用,总结了阵元中心距的最佳取值范围,为相控阵探头的设计和性能优化提供了依据和参考。
This paper took a one-dimensional ultrasonic phased array probe as an example ,began from the beam directivity function , analyzed the influence of the center distance of one-dimensional ultrasonic phased array probe on eliminating the grating lobe ,and pointed out the best value range of the center distance .The results could be used as a good reference basis for the design of phased array probe and its performance optimization .
