FOURFIT-A Computer Code for Determining Equivalent Nuclear Yield and Peak Overpressure by a Fourier Spectrum Fit Method

Abstract

A Computer code is presented which performs least squares fitting of simulated airblast pressure Fourier amplitude spectra. The code iteratively determines the simulated nuclear yield and peak overpressure of a record by the FOURFIT method of analysis by comparing the data spectra to the spectra representing candidate fits.
