Description These papers describe using of Hilbert transform in processing signal
received from standard mechanical impedance sensor. It’s shown that Hilbert
transform allows extract additional information from the signal and increase
reliability of non-destructive testing. Presented mathematical model of typical
signals received form mechanical impedance sensor and described ways to
extraction and using in non-destructive testing process wide known characteristic of
the signal like instantaneous phase and instantaneous frequency. Also described
another parameters based on mentioned characteristics which are more stable in
diagnostic decision-making compare to another widely used in contemporary flow
detectors. Shown experimental results obtained from scanning samples of
composite materials used in development of light-weight aircrafts.
