摘要

The study analyzes experimental data on amplitude-time parameters p(+), p(-), t(+), t(-), t(R+), t(R-) of the first positive and negative phases of acoustic waves in the atmosphere from different pulsed sources. The experimental data are compared with numerical simulation results for spherically and cylindrically symmetrical propagation of a blast wave in homogeneous air. Comparison reveals the features of how the stability of the atmospheric boundary layer influences the parameters and shape of acoustic signals propagating in it. Approximations are given for the experimental values p(-), t(-) and t(R-) of the recorded acoustic signals for a wide range of variations in the source energy values of 10(-8) < Q < 10(10) kg TNT and distances of 1 < R/Q(1/3) < 4 x 10(4) m/kg(1/3) to them.
