Effective Utilization of a Priori Information in Waveform Decomposition

We propose an effective algorithm of using a priori information in the problems of decomposition of seismic signals. The algorithm is realized in two steps. In the first stage there is defined a solution using pseudo a priori information, ensuring stability and uniqueness of the decomposition problem solution. In the second step we define a minimum quantity of available a priori information, which allows obtaining the exact solution of the corresponding problem. The latter is one of the principle moments for the waveform inversion using the real seismic signals.
