Abstract:

Using vertical ionograms to quantitatively determine radio frequency RF propagation conditions is a mature and well established technique. In principle, a large number of scaled vertical ionograms, and the electron density profiles that can be derived from them, along a specific path of interest would be required to completely assess the RF propagation conditions for that path. Typically, the midpoint ionosphere is a good approximation of the ionosphere along a specific path of interest and RF propagation conditions for that path can be determined from the scaled midpoint vertical ionogram. The difficulty of placing the required sounding hardware at the midpoint of a desired path can be resolved by developing a system capable of calculating the equivalent scaled vertical ionogram at the midpoint of a specific path Digital Oblique Remote Ionospheric Sensing DORIS program. A major component of DORIS is the development of an automatic scaling algorithm that can produce equivalent scaled midpoint vertical ionograms from oblique ionograms produced by a pair of Digisondes. kr
