This report results from a contract tasking Department of Electronic and Electrical Engineering, University of Bath, Claverton Down, Bath, BA2 7AY, UK as follows: The contractor will investigate the accuracy and improved performance in determining HF propagation by coupling a state-of-the-art ray tracing technique with a physics-based ionographic model. The accuracy of a novel segmented method for analytic ray tracing (SMART) developed at DERA is reported alongside numerical and virtual mirror ray tracing techniques. A description is given of a homing technique for the synthesis of oblique incidence (OI) ionograms by means of SMART ray tracing. Synthetic OI ionograms have been compared against measured OI ionograms on six UK paths. By scaling key parameters from each ionogram (synthetic vs. measured) the accuracies of four climatological ionospheric models, tomographic images and the Parameterised Real-time Ionospheric Specification Model (PRISM) are described.
