Quality Control Analysis of SUS Processing from ACODAC Data
Abstract
The errors associated with the analysis of acoustic signals generated by underwater explosive sources are analyzed in this report. Thus, the effects of analog reproduction and subsequent digital conversion of the data on the estimation of propagation loss are considered. In addition the techniques of the spectral analysis as applied to these data are discussed. It is shown that the digitizing processing can be repeated on a day-to-day basis to the extent that the energy in frequency bands for either shots or noise have standard deviations of 1 to 2%. The times at which the automatic shot processor detected a shot showed no fluctuations other than those to be expected from the temporal resolution imposed by the sampling rate. The standard deviations due to repeated processing of transmission loss for a given frequency band is of the order of 0. 1 to 0.2 dB.
