AN ANALYSIS OF A TECHNIQUE FOR THE GENERATION OF HIGH RESOLUTION WAVENUMBER SPECTRA

Abstract

In this report, we discuss a method of obtaining a high-resolution wavenumber spectrum of time series data obtained from a seismic array. We derive the theoretical high-resolution wavenumber spectrum of both a single plane-wave event and an event made up of the sum of two plane waves of different amplitudes. We then process the two theoretical events and analyze the results. The plane waves for both events are simulated by impulses, with time delays between sensors chosen to simulate move out across the array. We also process the LONG SHOT event.
