Multiple Phase-Screen Propagation Analysis for Defense Satellite Communications System

Abstract

This report presents and analyzes simulated results for electric field propagation through a thick, extended region of high-altitude striations of electron density. The simulated results correspond to the problem of communication from a DSCS satellite to a ground station at a frequency of 7.5 GHz. Statistical results are presented for S4 scintillation index and intensity correlation length for a power-law and an exponential phase-screen PSD for values of phase standard deviation ranging from 1 to 100 radians and phase correlation length ranging from 1 to 10 km. Examples of specific realizations of the electric field amplitude and phase at the receiver are also shown. These realizations of signal structure are being used in simulations of DSCS receiver operation, reported elsewhere.
