This article studied the phase detected signals for problems ultrasonic testing of composite materials on the background of additive Gaussian noise. The study was different relations period carrier-frequency, pulse signal and the size of the sliding window of numerical averaging. Simulations performed on the system Matlab.
detector phase, the phase characteristics of the signal, Hilbert transform
