A Description of the NRL Oblique-Incidence-Ionogram Data Base.

Abstract

Since 1980 the Naval Research Lab. has been engaged in a number of field experiments during which sequences of oblique-incidence ionograms have been obtained. Data has been accumulated in both analog-photographic and digital form with the majority of the earlier data sets being of the former category. Approximately 50,000 ionograms have been archived for analysis purposes. This report outlines the texture of the data base indicating the mix of properties which may be employed to partition the data. Originator-supplied keywords include: Oblique-incidence sounding, HF, Frequency management, and Data base.
