FIELD: testing technology.
SUBSTANCE: method of filtering non-stationary signals is performed by correlation reception of pre-recorded on the data medium, followed by isolation of the desired signal, and search for the desired signal is carried out simultaneously with memorization of instantaneous values of the correlation function and the spectral density of the signal, their comparison and identifying differences between the respective characteristics from stationary signs, and evaluation of amplitude-frequency range of the desired signal is carried out.
EFFECT: extraction of non-stationary signals having limited duration, of arbitrary shape and frequency spectrum.
