SPECTRUM AND OCTAVE BAND ANALYSIS OF PRESSURE PULSES FROM DEEP UNDERWATER EXPLOSIONS

Abstract

Fourier spectra were computed on the IBM 7090 for analog tape recorded pressure pulses of underwater explosions fired at sea in February 1965. Depths ranged from 500 to 14,000 feet; charges weighed 1 to 88 pounds; the compositions fired were TNT, pentolite, HBX-3, and Nitramex. Reduced spectra of charges weighing up to 57 pounds agreed with previous results from 1 and 10 pound charges at the same depths. Only slight differences due to composition were found.
