The Effects on Antenna-Filtered Scintillation Parameters of Non-Zero Antenna Pointing Angles

Abstract

In this report the antenna-filtered generalized power spectral density function (GPSD) for strong scintillation is derived for the general case of two different Gaussian antennas pointed in arbitrary directions relative to the transmitter-receiver line of sight. From the GPSD we obtain the normalized signal decorrelation coefficient and the filtered decorrelation distance and time. Expressions are also derived for the antenna power loss, the filtered frequency selective bandwidth, and the power impulse response function. The results are completely general with respect to pointing angle and the orientation of the antenna relative to the ionization structure. Finally, the power impulse response function is generalized to obtain the signal correlation as a function of delay at two different antennas. A method of using a complete set of correlation coefficients to generate signal realizations for a collection of antennas is outlined. Keywords: Antenna pointing angles; RF Propagation; Antenna-filtering; Physics; Optics; Electrotechnology; Scintillation; GPSD.
