Paper Abstract

The paper presents the results of the wavelet analysis of infrasound signals from ground-based low-power explosions. It was found that in most cases, the spectral structure of the infrasound signal has the character of a monotonic decrease of the oscillation period. For these types of signals from the explosion with the power tab order of 0.01 × 10-3 kT at a distance of up to 300 km infrasound signal spectral structure has the character of a linear decrease of the period of pressure fluctuations from time to time according to the law T = Т0 - B × t, where the most probable values of the initial period Т0 take values from 0.97 and index decreasing in the period - 0.25.
