本文叙述米波、分米波电视天线和调频天线服务区场强的工程计算法。文章从电视发射台的实际情况出发,介绍了电波受地物、气象等影响时的场强计算方法和半阴影区的近似场强计算方法等。还介绍了在城市的电波计算中,引入“建筑物密集度”参数的场强计算方法。
This article describes the engineering calculation method for the field strength of the microwave, the decimeter TV antenna and the FM antenna service area. Based on the actual situation of the TV transmitter station, this paper introduces the calculation method of the field strength when the electric wave is affected by the ground objects and meteorology, and the approximate field strength calculation method of the semi-shadow area. Also introduced in the city of radio calculations, the introduction of “building density” parameter field strength calculation method.
