Аннотация
This study investigates a directional fading model for narrowbeam receiving antennas, typical of user terminals in modern satellite communication systems. Through analytical simplification, we derive an approximate version of the original model, where the power spectral density of the fading process is approximated by a Gaussian function. This approximation enables a computationally efficient synthesis method for the target application scenario. To validate the synthesized process, we compare its level-crossing statistics with theoretical predictions from a generalized reference model. Additionally, we propose a heuristic expression for a key model parameter controlling the angular spread of fading components. This expression is formulated in terms of physical parameters defining the radiation pattern of parabolic antennas, which are widely used in satellite terminals.
