Abstract

An additive least-squares-method algorithm was developed for spectrally estimating unknown parameters of a geophysical signal on a background of steady-state noise having an unknown spectral density. The algorithm was tested using data of regime observations of lithospheric deformations in the Elbrus region obtained using a deformation measuring Baksan laser interferometer (deformograph). The algorithm was used to estimate the parameters of the natural oscillation modes of the Earth excited by strong earthquakes.
