f ESTIMATING THE SEISMIC SOURCE SPECTRUM AND RADIATION PATTERN FOR A MULTlDIMENSIONAL EARTH

Estimating the seismic wavelet and radiation pattern is useful in traditional seismic processing and is very important in AVO and migration/inversion methods. The wavelet estimation method presented here is a wave theoretic approach which for each source array requires the total field and its normal derivative along the receiver line. The method allows the subsurface to be arbitrarily inhomogeneous and anisotropic without requiring any information about the subsurface. The medium above the receivers must be known.
