摘要
超短波地空通信是地空通信中的重要组成部分。理论分析了飞行遮挡对超短波地空通信的影响,建立了飞行遮挡模型,定量计算出运输机飞行遮挡时对地空通信效果的影响,用实测数据验证了理论分析及建模的正确性。为规避飞行遮挡对超短波地空通信造成的影响具有一定的指导作用。
The VHF air-ground communication is an important part of air-ground communication.First,the flight shielding effect on VHF air-ground communication is analyzed by theoretical method;then the flight shielding model is established and the quantitative calculation of flight shielding effect on air-ground communications effectiveness for a transport airplane is implemented;finally, the model and the analysis is verified by the measured data.The results play a role in avoiding the flight shielding effect on VHF air-ground communication effectiveness.
