摘要

利用Ｆｒｅｓｎｅｌ－Ｋｉｒｃｈｈｏｆｆ原理得到了计及地面反射时多刃峰绕射场求解公式，用该式对导体劈、平顶直边和平顶斜边障碍物绕射场进行了求解。导体劈与平顶直边障碍物绕射场的数值结果分别与ＧＴＤ和Ｊ．Ｈ．Ｗｈｉｔｔｅｒｋｅｒ的理论所得结果和实验结果进行了比较．本文所给公式简洁，物理概念清晰，克服了ＧＴＤ处理过渡区场的困难，便于工程技术中应用。

Abstract

Based on Fresnel-Kirchhoff principle

a general representation of field of diffraction by multiple knife-edge is given under the condition of existence of ground reflectio. Meanwhile

a way of sloving the diffraction field by a flat-topped obstacle with bevel edge is obtained. The method is to find the sum of the field of eight rays. The formulas we got are convenient for practical caculation and have clear physical conception.
