The determination of the ionospheric perturbation degree is essential to describe the ionosphere state for space weather monitoring. A new method for estimating the spatial and temporal components of the Vertical Total ...
A flatness-based generalized optimization approach to spectral estimation
(1990-04)
Article.
Accés obert
Article.
Accés obert
In the optimization formulation, once the known autocorrelations are fixed as constraints, the objective functional completely characterizes the corresponding method of spectral estimation. After observing that this ...
