Web1 mei 2012 · Ray tracing (RT) is a numerical technique used to determine the path of a high frequency (HF) radio wave in anisotropic and inhomogeneous media different from vacuum (Budden, 1988). The technique works properly if the refractive index is assumed to be known in each point of the considered region. WebСмотрите онлайн КАК УСТРОЕН ray tracing? 17 мин 58 с.
