Abstract:

In this paper, we analyze statistical characteristics of envelopes of acoustic signals propagating along short near-surface paths. Experimental data are processed to study the density of probability distribution of envelopes for carrier frequencies of 500 and 5 000 Hz. The repetition of the considered distributions is determined, and their correlation with turbulence is estimated.

Keywords:

atmosphere, sound, propagation, envelope, statistics, turbulence
