Paper Abstract

We investigate the estimation of both the number of waves and the wave parameters for transient wavefields in a geophysical application. Models of the earth have to be verified by seismogram analysis. We present two nonparametric methods for the estimation of wave parameters where one is based on the first-order stationary spectrum and the other one is based on the second-order cumulant spectrum. We also investigate a parametric method for wave parameter estimation which allows us to determine the number of incident waves. The algorithms are applied to synthetic seismic data.
