Ionospheric ray tracing

WebPHaRLAP is Matlab toolbox for the study and modelling of the propagation of High Frequency (HF) radio waves in the Earth's ionosphere. It provides 2D and fully magneto-ionic 3D numerical ray tracing (NRT) engines, analytical ray tracing (ART) routines and the necessary supporting routines. Web1 feb. 2024 · Digital ray tracing studies are mainly concerned with two-dimensional tracing that ignores geomagnetic field influences and collision effects (Coleman, 1997, Coleman, 1998, Zhong et al., 2001). If these are to be considered, as well as the non-uniform ionosphere, 3D digital ray tracing must be taken into consideration (Jones, 1968).
