摘要
文章介绍ITU -R建议中五项电波传播技术模式的研究情况。它包括对流层散射传输损耗统计预测方法、海事卫星移动通信海面反射衰落预测方法、电离层闪烁衰落换算方法。
Studies are presented on five radio propagation models in ITU-R recommendations. The models include statistical prediction method for tropospheric scatter transmission loss, prediction method for sea reflection fading in maritime mobile satellite telecommunications, conversion method for ionosphereic scintillation fading, simplified prediction method for attenuation by atmospheric gases and modified prediction method for field strength in land mobile services.
