Blind Deconvolution Algorithm Based on Optimal Wiener Filter
This program implements a blind deconvolution algorithm utilizing optimal Wiener filtering. Wiener filtering transforms seismic wavelets into any desired waveform shape. Similar to inverse filtering, a Wiener filter can be designed to convert seismic wavelets into spike pulses. However, Wiener filtering differs from inverse filtering by achieving optimality in the least-squares sense. The algorithm implements the well-known Wiener-Levinson approach for filter design. The program provides five target output options: zero-delay spike pulse, arbitrary-delay spike pulse, time-advanced input sequence, zero-phase wavelet, and custom desired waveform.
