Abstract
In this paper the main problems that appear in measurement of time-of-flight intervals in acoustic tomography are analyzed. They are related to the influence of noise and with a limited slew rate of the signal amplitude envelope. The method based on linear modulation of the acoustic pulses period is proposed. Correction of directly measured time interval is based on the additional measurement of duration of the given number of half periods of received signal when the signal envelope is stabilized at a sufficient level. The efficiency of proposed method of correction is investigated by simulation.
