Abstract EN
The analysis of interaction of ultrasonic pulses with different reflectors which are located in elastic media is carried out.
A parameter which allows estimating the form of reflector is instantaneous frequency of pulse-echo.
This parameter is an unsteady pulse echo characteristic.
Instantaneous frequency determination algorithm is to use wavelet transformation which has increased noise immunity.
It is shown that the instantaneous frequency value for a pulse echo is often shifted from a rated frequency of piezoelectric transducer.
Difference between the frequencies extensively depends on the reflector form.
