Abstract

Recently published results on D-region partial-reflection amplitude distributions indicate that below 80 km, the distributions are Rayleigh-like in character. Because of this, this paper describes a model of the partial-reflection mechanism which employs multiple reflectors as opposed to the single-reflector concept now in use by most experimenters using the partial-reflection experiment. The particular new feature incorporated by this model is the variation of the reflection coefficient throughout the reflecting volume; previous multiple-reflector models considered only the variation of the differential absorption in the reflecting volume. It is shown, for example, that for 50-μsec pulse lengths, serious errors in electron density can result in the analysis of partial-reflection data for which multiple reflectors are present.
