摘　　要：在低仰角条件下,对短脉冲微波传播中出现的遮挡、多径到达和天线波束分裂现象进行了分析,分别应用透波屏模型、Fresnel半径模型和两路径模型描述这三种现象,结合工程实践估算其产生的影响,并提出了应对措施。In this paper, the three phenomena of shadowing, multipath, and splitting of antenna beam are analyzed under the condition of low elevation. Penetrating wave screen model, Fresnel radius model, and two-path model are used to describe the three phenomena, respectively.The influences of the three phenomena are evaluated according to the engineering practice, and some useful suggestions are proposed.
