First experiences of full-profile analysis with GUISDAP

[摘要] In this paper we summarize the theory behindfull-profile analysis of IS measurements and report firstpractical experiences with the GUISDAP (Grand UnifiedIncoherent Scatter Design and Analysis Package) systemdesigned to perform full-profile analysis of any ISmeasurements efficiently. By fitting whole plasma parameterprofiles over the ionosphere, instead of point valuesof the parameters supposed to be approximately constantover small range intervals, full-profile analysis is free ofunderlying assumptions about the slow variation of theplasma parameters as a function of range. We definefull-profile analysis as a mathematical inversion problemformalism and explain how it differs from the traditionalgated analysis. Moreover, we study the bias introduced totraditional analysis results using realistic model ionospheres.By applying the full-profile method to data generatedfrom the model ionospheres, we demonstrate thatfull-profile analysis is free from this kind of bias. Lastly, anexample of analysis of real data by full-profile and gatedanalyses is shown.
