摘　　要：随着对流层散射理论和技术的发展,其在通信领域中的应用越来越广泛,成为研究的热点问题。影响对流层散射传输损耗的因素较多,本文依据ITU-617建议书中的模型,进行对流层散射传输损耗分析,比较了不同频率、传输距离和地球有效半径因子下对流层散射传输损耗的变化情况,仿真结果表明,地球有效半径因子是影响对流层散射传输损耗数值的重要因素,为精确计算对流层传输损耗、有效利用对流层散射通信提供了理论参考。With the development of tropospheric scattering theory and technology,its application in the field of communication is becoming more and more extensive,and it has become a hot issue of research.There are many factors that affect the tropospheric scattering transmission loss.According to the model in Recommendation ITU-617,this paper analyzes the tropospheric scattering transmission loss,and compares the changes of the tropospheric scattering transmission loss under different frequencies,transmission distances and effective radius factor of the earth.The simulation results indicate that the earth’s effective radius factor is an important factor that affects the value of tropospheric scattering transmission loss,which provides a theoretical reference for accurately calculating tropospheric transmission loss and effectively using tropospheric scattering communication.
