摘要
劈形与刃峰绕射场在远区是一致的,均可用一个非常简洁的公式表达出来,障碍物形状对远区场的影响是比较小的;在绕射区(相对余隙v>1),刃峰绕射场可用公式12.95+20logv表达,比CCIR[1]中表达式更简洁,便于工程应用。
An uniform expression of wedge and knife-edge diffraction fields is obtained. As to far field, the shape of the obstacle has a little affection on its diffraction field. An knife-edge diffraction field can be expressed as 12.95 +20logv which can be more convinently used in comparision with CCIR[1]
