摘要
本文详细阐述了地面反射波位置、地形阻挡和未阻挡条件下主反射波损耗、反射波波簇影响的计算方法,提供了相应的依据和结论,并对所涉及问题进行了危害影响分析,同时说明了解决问题后获得的实际效果。本文还为每个应用案例提供了计算示例,以期为广播电视微波链路传输实践提供借鉴。
This article elaborates on the calculation methods for the loss of main reflected waves and the impact of reflected wave clusters under the conditions of ground reflection wave position,terrain obstruction,and unobstructed conditions,providing corresponding basis and conclusions.It also conducts a hazard impact analysis of the involved issues and explains the actual effects obtained after solving the problems.This article also provides calculation examples for each application case,in order to be used as a reference for the practice of microwave link transmission in broadcasting and television.
