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.4200004 bytesapplication/pdf論文公開時間: 2017/2/15論文使用權限: 同意有償授權(權利金給回饋學校)電離層不規則擾動相位閃爍全球定位系統電離層傳播ionospheric irregularitiesfluctuationsphase scintillationGPSionospheric propagationthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/276723/1/ntu-104-R02942091-1.pdf
