研究目的
Investigating the effects of Faraday rotation and path delay on electromagnetic waves propagating through the ionosphere, and developing a vectorized model for a large-field-of-view, low-Earth-orbit satellite system to estimate these effects based on global position and geometric parameters.
研究成果
The research presents a vectorized model for estimating Faraday rotation and path delay over a large field of view for low-Earth-orbit satellite systems. The model demonstrates favorable correlation with existing theoretical models but diverges in overall field-of-view patterns due to its vectorized approach and geometric calculation of propagation path. The model extends the estimates of these effects into three dimensions, considering the non-uniform nature of the ionosphere according to height and global position.
研究不足
The model's accuracy is dependent on the resolution of total electron content data and the assumption of a daytime maximum profile of the ionosphere. Future revisions may need to address the coarse data for total electron content, the time-varying nature of the ionosphere, and the validity of magnetic field vector data at very low levels.
