Modelling the radiowave propagation with a split-step wavelet method for radio occultation

Abstract : This paper introduces the split-step wavelet (SSW) propagation technique applied to radio occultation (RO). This technique accounts for both a complex atmosphere and the ground reflection. It is applied on a scenario between a GPS satellite and a low-elevation orbit satellite. The atmosphere is modelled using an ITU model. The Earth is considered as a sphere. We show that the atmosphere and ground effects are both visible at the receiving satellite. Therefore, SSW is a good candidate for RO propagation modelling.
