Abstract
A methodical system has been developed to solve the problem of isolating informative signals against the background of noise which is based on a morphological analysis. It is shown that the morphological method of analyzing infrasonic signals is an effective instrument to isolate infrasonic signals, to analyze the features of their forms, and to estimate their relative delays. The advantage that the morphological method has over the correlation method in analyzing short signal fragments recorded by infrasonic microphones spaced at distances that significantly exceed the signal wavelengths is shown.
