摘要

摘要 在双射线模型中研究了超宽带(UWB)波在地球表面的传播特征。研究表明,由于超宽带波的自相关时间极短,因此存在一个极限距离(断点),在此距离之前,超宽带波的衰减近似于自由空间中的路径损耗指数 n = 2,而不会出现衰减;在断点之后,波的衰减指数变为 n = 4。

Investigation of the Attenuation Rate of a Ultrawideband Wave Outdoors in a Two-Ray Model

Abstract

The features of propagation of an ultrawideband (UWB) wave over Earth’s surface in a two-ray model are studied. It is shown that there is a limiting distance (break point) up to which the UWB wave attenuates approximately as in free space with pathloss exponent n = 2 without experiencing fading due to the extremely short UWB autocorrelation time; beyond the break point, the wave attenuation exponent becomes equal to n = 4.
