Titov, R. Maev, A. Bogachenkov] A pulse broadband gauge designed for measurements of the velocities of surface acoustic waves is described. The gauge's output signal is formed during mechanical translation of focused ultrasonic transducers relative to a specimen under study placed in an immersion liquid. A design of the device with line-focused lensless ultrasonic transducers for the frequency range 2-25 MHz is considered. The results of measurements of test samples are presented, and the algorithms for processing the output spatial-temporal signals for determining the frequency dependences of phase velocities of acoustic waves are described. Using a carbon steel sample as an example, it is shown that the random error component in acoustic-wave velocity measurements can be estimated as ±(2-8) and ±(1-3) m/s for longitudinal and lateral scanning modes, respectively.
