The troposcatter loss estimation by the uniform path-loss model based on power balance theory

Abstract

This paper presents a median troposcatter path loss model by the uniform path-loss (UPL) model based on power balance theory (PBT), theoretically. Firstly, the tropospheric forward scatter cross section of the common volume is adopted in the UPL. Secondly, ITU-R P.617, ITU-R P.452 and NBS-101 are compared with this theoretical prediction model. Thirdly, the tropospheric scatter loss experiment outcomes in northwest China at L band are used to verify the effectiveness of the basic loss predictions. It is found that the suggested model is an accurate model compared to the empirical models, i.e., ITU-R P.617, ITU-R P.452 and NBS-101, for not only the trans-horizon link, but also the relatively high scatter angles link, i.e., the obstacle crossing short jump mode. And the TSUPL-H is found to be well-fitted with the median troposcatter path-loss L band experiment data in the northwest China.
