THE METHOD OF FRACTAL IMPULSE DECONVOLUTION

WANG JIA-SONG (Mathematics Department , Nanjing University, Nanjing 210093, China)CAO GUI-RONG (Research Group of the Information Natwork, Nanjing Institute of Posts and Telecomnmmication, Nanjing 210003, China)  
To solve the seismic inverse problem, impulse deconvolution method is based on the assumptions that the reflection sequence is white noise and the wevelet has the property of least phase. Latest research has shown that the reflection sequence is fractal noise rather than white noise. Upon this fact some researchers have brought out a kind of methods called fractal deconvolution methods which turn the seismic inverse problem into a system of nonlinear equations difficulty to solve. Using fractal properties of reflection sequence, this paper deduce a much simple system of linear equations which is easily solved. Numerical results illustrate that this method is efficient.
