摘要: | Phase scintillations of GPS signals caused by ionospheric irregularities in the equatorial and polar regions are simulated and analyzed. The electron density irregularities in the ionosphere are modeled with different spectra, and realized with a Monte-Carlo technique. A parabolic wave equation (PWE) technique is then applied to compute the field distribution of GPS signals as they propagate through the ionosphere. The simulated phase scintillation in high-latitude regions is much more obvious than that in the equatorial region. |
