Statistical Analysis of an Over-the-Sea Experimental Transhorizon Communication at X-band in China

Abstract

Refractive index structure of the atmosphere plays a dominant role in influencing signal levels associated with terrestrial communication systems. In 1990–1992 and 1997, some experiments were conducted to analyze a refractive index structure and occurrence probability of evaporation duct on East and South sea area of China. On summer in 2004, an over-the-sea experimental system was designed to analyze an X-band transhorizon communication. This paper describes statistically the features of measured signal, such as fading distribution, fading amplitude and fading excess. Preliminary results describing the statistical characterization of the channel are presented.
