Abstract
The possibility of estimating the parameters of surface pulsed sources from data on acoustic waves recorded in the atmosphere is studied. Experimental values are given for peak pressure P+ of recorded acoustic signals, wave-profile area S+ in their positive phase, and length t+ of this phase, and the approximations of these parameters are obtained within wide ranges of source energy 10–3 < E < 1010 kg TNT and scaled distances 1 < R/E1/3 < 4 × 104 m/kg1/3. Conventional methods of estimating the acoustic energy E according to data obtained from acoustic measurements in the atmosphere are analyzed, and ways to improve their accuracy are proposed. The influence of the type of explosions on the parameters P+, S+, and t+ of acoustic signals at long distances R/E1/3 > 500 m/kg1/3 from explosions is shown.
