The results of analysis of the possibilities to use Complex-Modulated radio pulses as probing signals in US flaw detection are given. It is shown that the application of Complex-Modulated echo signals in the receiving path optimal filters improves the basic parameters of the echo control method – sensitivity and resolution capability, and, in presence of white noise and not correlated interference, generally increases the reliability of the testing method.
