Drifting Ionospheric Scintillation Simulation for L-Band Geosynchronous SAR

“…According to (5), the diffraction merely changes the highfrequency components because of the interaction of the square cosinusoid, and thus will not significantly change the PS-SPE, which indicates that the PS-SPE approximates to the STF-SPE [31], [36], [37]. According to (6), the SDF of the logarithmic amplitude is modulated by the square sinusoid, and therefore the spatial structures larger than the first Fresnel cutting scale become dominant in the amplitude pattern, which makes the high-frequency components more significant and contributes to the bright-dark amplitude stripes [47].…”
