中文摘要: |
本文计算了在频率为1-300GHz(波长为0.1cm-30cm)的微波在大气和云雨中的吸收、散射和衰减的效应.统计和分析了北京地区降雨分布特征,对于地面-卫星通信线路衰减作了预测,为北京地区地面-卫星通信工程设计提供了重要依据.本文提出了新的地面-卫星线路衰减的预报方法,较为准确,可供卫星微波通信工程中使用. |
英文摘要: |
In this paper, the attenuation absorption and scattering effects of cloud and rain m microwave and, frequency:1-300GHz (wavelength:0.1 cm-30 cm),have been calculated. The rain rate statistics and analysis in Beijing District have been treated. The effects of cloud and rain on satellite-earth microwave communication are discussed. It is important for engineering design of satellite-earth communication. In this paper, a new method for prediction of the attenuation of satellite-earth microwave communication is given. It is more accurate and convenient for engineering design. |
