| Zusammenfassung |
| In this paper we summarize the theory behind
full-profile analysis of IS measurements and report first
practical experiences with the GUISDAP (Grand Unified
Incoherent Scatter Design and Analysis Package) system
designed to perform full-profile analysis of any IS
measurements efficiently. By fitting whole plasma parameter
profiles over the ionosphere, instead of point values
of the parameters supposed to be approximately constant
over small range intervals, full-profile analysis is free of
underlying assumptions about the slow variation of the
plasma parameters as a function of range. We define
full-profile analysis as a mathematical inversion problem
formalism and explain how it differs from the traditional
gated analysis. Moreover, we study the bias introduced to
traditional analysis results using realistic model ionospheres.
By applying the full-profile method to data generated
from the model ionospheres, we demonstrate that
full-profile analysis is free from this kind of bias. Lastly, an
example of analysis of real data by full-profile and gated
analyses is shown. |
