Definition of a quality factor for single site location estimates
Coetzee, Petrus J.; Du Plessis, W.P. (Warren Paul)
A technique to estimate the performance of Single Site Location (SSL) based on High
Frequency (HF) direction finding (DF) for reigning ionospheric propagation
conditions is described. This technique is based on classic propagation information
(MUF, FOT, OWF, HPF, LPF, etc.) which can be deduced by ray-tracing through an
ionospheric model such as the International Reference Ionosphere (IRI). The
correlation between the elevation angle measured by an interferometric direction
finder and the angles corresponding to the propagation conditions are used to assign a
quality factor to the calculated SSL ground range result.
