Filed: 2017-11-02
Abstract: To provide a method for estimating a wave propagation time between two points in a medium that propagates a wave.SOLUTION: The fact that a wave propagates between two points is considered. Assuming the respective positions as x and y, a cross correlation function of the waveform observed at the respective points is calculated. With a waveform at a point j of time at the position x used as a point of reference, a relative error function between this waveform and a waveform at a time i traced back from some point of time j at the position y is fluctuated in units of time i as a sample time interval, and the time i at which the absolute value of the relative error function becomes minimum is a wave propagation time at some point of time j. In actual processing, the relative error function is calculated in plurality for the case where a waveform at the position x is made a point of reference and the case where a waveform at the position y is made a point of reference tracing back a time difference i in units of sample time, respectively.SELECTED DRAWING: Figure 1
