| 摘 要： | 为分析飞行器位置、姿态和工作频率对航空超短波通信链路性能的影响,构建了航空超短波通信链路模型,利用FEKO7.0电磁仿真软件计算了机载天线与飞行器一体化电磁辐射特性,基于MATLAB软件设计了系统的主程序,系统主程序通过调用天线的辐射特性数据,结合飞行器的位置、速度和姿态变化,可计算出通信双方之间的天线极化衰减和空间衰减等数据,分析了飞行器在相应状态下航空超短波通信链路性能的数值变化,具有较强的实用性。

| Abstract: | A link margin analytic modle is built for aeronautical VHF communication in order to analysis the influence of aircraft position and attitude and frequency on link margin. The radiation quality of the one-body of airborne antenna and aircraft is calculated. The main software program is designed based on MATLAB. The polarization attenuation and space attenuation between the transmitter and receiver can be calculated along with the change of the aircraft position and attitude and frequency. The change of the link margin of aeronautical VHF communication is validated in the last paragraph of the article. The system is very practicable. |
