Abstract
A new simulation method for sky-wave OHTR ionospheric channels is developed. To make the simulation more robust, the International Geomagnetic Reference Field (IGRF) model and International Reference Ionosphere (IRI) model are integrated with a classical 3D ray tracing code firstly. After numerical ray tracing, a new algorithm for matching outbound raypaths with returning raypaths is developed. The channel simulation is established with the consideration of the Doppler-space-delay correlation. Stochastic channel generated by this simulation can be used for OTHR design and signal processing research. (6 pages)
