Abstract:
Methods are presented which permit the calculation of signal structure properties of satellite signals as they propagate through structured ionization. The primary parameters are the signal decorrelation time, the frequency selective bandwidth, the mean square log amplitude fluctuation, and the mean square arrival angle of the signal. The form of the generalized power spectrum, which characterizes the arriving signal as a function of frequency and delay, is specified in terms of the calculated signal structure parameters. Finally, methods are discussed to generate using Monte Carlo techniques signal structures from the generalized power spectrum.
