| Abstract: | Based on the damped wave equation,the damped wave equation for seismic exploration is given for the study on evaluation problem of stratum acoustic impedance by the seismic data records.And applying Cauchy Problem instead of mixed problem in the process Of identifying acoustic impedance,we for give a fast identification algorithm of recurtive layer by layer.In order to avoid the accumulation of errors while identifying,the method of removing errors layer by layer is taken.So using the principle of Pulse Variation and even under the circumstance of big noise,we can identify the structure of stratum clearly. |
