Novel Statistical Approach to Blind Recovery of Earth Signals and Source Wavelet

Seismic signals are a convolution of a source wavelet and the response at each earth layer boundary. Despite attempts to record the outgoing source wavelet at the surface, often little is known of the source wavelet at depth, and there is no a priori knowledge of the earth response or the noise. Current practice makes the basic assumptions that the source wavelet is known, and the noise can be neglected.
