Comparison of Some Theoretical Noise Models with the NORSOR Microseismic Noise Field

Abstract

The effectiveness of large arrays in mapping the noise field is well known. The paper describes an attempt to estimate the noise field by using a small number of sensors. The noise fields are defined by their power densities in the frequency-wavenumber space and their validity will be judged by comparing coherence estimates of real data with coherence computations on the basis of the models. The real data-base have been recordings from Oyer array - the first large installation in the NORSAR area.
