On the Interpretation of Ionospheric Scintillation Data Using a Power-Law Phase Screen Model--Weak Scatter
Abstract
An equivalent phase screen model is used to interpret the Wideband satellite data under conditions of weak scattering where the intensity scintillation is such that S sub 4 is < or approximately 0.4. The phase spectral density is fitted to a power-law model of the form TF(to the -p power) to obtain the basic parameters T and p. The phase screen model is then used to remove the geometrical dependence of T. An invariant strength-of-turbulence parameter can be obtained from such an analysis. By using the phase-screen model, the Wideband rms phase and intensity data have been self-consistently calculated, thereby verifying the validity of the model. The results are used to calculate the rms electron density perturbation levels required to produce significant gigahertz scintillation. (Author)
