中文摘要:
      许多超声检测都是通过测量声波传播速度来实现的。本文报道了一种基于脉冲回波相位谱的超声波速度测量方法,并给出了它的详细理论推导过程。若干模拟计算结果显示了这种方法对频散及非频散介质的声速测量都适用。
英文摘要:
      Ultrasonic sensor measurements are mostly based on the determination of the propagational speeds of waves. This paper presents the development of a pulse-echo measurement method, based on the use of a phase spectrum to determine the ultrasonic wave velocity. A detailed descripsion of the theory is given. Some simulated results have been shown that the method can be used to measure the speeds of waves in nondispersive and dispersive medium.
