Approximation Approach in Dynamic Analysis of Multichannel Seismograms 1. Model Conceptions

A new approach to interpretation of the reflection survey data obtained from the multiple overlapping spreads (type of CDP) is proposed. The approach concept consists in derivation of two approximation models, of the field and of the medium, whose parameters are interlinked. This part of the work considers a relationship of these approximation models and the model derived on their basis for describing the parts of seismic traces which contain the signals reflected from thin-layer units. The last model provides the basis for development of estimation techniques of source parameters of approximation models. The techniques will be considered in the next part of the work.
