DIGITAL EVALUATION OF A CALIBRATION TECHNIQUE FOR MULTIPLE-ELEMENT ARRAY SYSTEMS
Abstract
A quantitative analysis was made using techniques of digital spectral analysis. Two different approaches were compared -- statistical and deterministic. For the statistical approach, the computer program 'BLACKY,' which computes power density spectra, was adopted. The program 'NUTRAN' which uses the Numerical Transform Theorem (Huang, 1965a) was written for the CDC 160A digital computer and relies on a deterministic consideration of a time series. The agreement between the field calibration and the estimation of the magnification curve is good up to 1.5 cps, considering the simplicity of the mathematical model used in the study. Above this frequency, the scatter is quite erratic, and further refinement of the technique is desirable. Disagreement comes essentially from a lack of the high signal-to-noise ratio.
