Introduction:
The Model-Based Wavelet Processing system is an wavelet processing expert's toolkit. The system allows the user to construct almost any possible wavelet producing system, impulsive or vibroseis. The user can hypothesize probable systems and vary the parameters of unknown components to produce residual wavelets and residual error wavelets for analysis. The system allows for single-trace SEGY input and output for use in processing systems. Resultant wavelets can be signal-processed (typically deconvolved) by the deconvolution algorithm used in your processing system. Scripts for creation and processing of wavelet components can be saved in the Database Handling system for future use. Example scripts for dynamite and vibroseis systems are included.

Model-Based Wavelet Processing System Components
The Model-Based Wavelet Processing system includes:
1. Modules: See Attached List ((Windows NT/2000 Operating Systems, or any Unix operating System)
2. Database Handling System: Holds WPPL (Wavelet Processing Programming Language) Scripts and is a database that documents your wavelet processing templates and particular wavelet processing scripts for particular jobs. (Windows NT/2000 Operating Systems).
The system is available in a run-time version and a source-available versions. The runtime version includes C-Language templates for you to construct your own modules.
