一种对流层散射通信斜延迟估计方法
An Estimation Method of Slant Delay in Troposcatter Communication
摘要
Abstract
In order to realize real time troposcatter communication,a method for calculating troposcatter communication delay without channel measurement is proposed. First,the meteorological data is calculated by Global Pressure and Temperature 2(GPT2) model.Then,the troposcatter communication delay is calcu-lated based on ray tracing method. The calculation result with the data of three typical measuring stations in China is coincided with the actual distribution characteristics of tropospheric delay in China. This meth-od is a hybrid method combining the GPT2 model and ray tracing which avoids the dependence on sounding data. This paper offers a new idea and method for calculating the troposcatter communication delay without channel measurement.关键词
