dc.descriptionAbstract: A Wiener filter is a mathematical operator designed to convert a given waveform (the filter's input) into another waveform (the filter's output) which is as similar as possible, in the least squares sense, to a third waveform (the desired output). Because filter theory might have application to the problems of explosion effects testing, a computer program has been developed to construct these operators for use in ground shock investigations. This report reviews convolution, crosscorrelation, and autocorrelation, the time domain operations which are basic to the Wiener technique, and shows by examples the operating characteristics of the program. It is concluded on the basis of work seen during the development of the program that digital filters may be used to define, accurately and economically, many important explosion effects relationships. Examples are included to demonstrate the fact that ground shock time histories may be estimated in uniform soil and rock using these operators to adjust for relatively large gage range and depth differences in the high pressure airblast region.
