Estimation of Parameters of Non-stationary Geophysical Signals Based on Two-Stage Approximations Using Local Models
The authors have developed a technology for estimating the parameters of non-stationary geophysical signals, using a two-stage approximation with local approximation models at the first stage and weighted averaging at the second stage. This article considered an example of estimating the amplitude, frequency and trend parametric functions for geomagnetic pulsations Pc1.
