An Analysis of Polar Cap Backscatter Radar Data
Abstract
A simplified analysis was performed as a preliminary to a more elaborate analysis of data from an FM/CW backscatter sounder experiment known as RECAP in the polar winter ionosphere. The results show that a reasonably accurate simulation of ionogram data can be achieved with the simple procedure and these results are of value in themselves. A brief survey of the morphology of the polar winter ionosphere is included as an aid to further data interpretation. Particular attention was paid to the question of clutter, and a model for the different kinds thereof is presented. The suggestion that active control of the antenna radiation pattern may be used to mitigate against clutter degradation in an OTH backscatter radar was examined and found to have merit. Finally, the question of the observed signal strength characteristics was addressed and a model for non-deviative absorption is presented.
