Spectral Correlation Models of fluctuations in the Earth's Rotation

摘要

Spectral and spectral correlation methods of processing measurements of the Earth's motion are commonly used to develop models of oscillations of the Earth's pole [1-3]. Linear and nonlinear analytical stochastic models of the motion of the deformable Earth were developed in [4-7] on the basis of celestial mechanics. In this paper, we construct spectral correlation models of fluctuations in the Earth's rotation and analyze the spectral correlation characteristics of fluctuations.
