由于高层建筑物对电视电波的反射,在来波方向建筑物的背后形成电波场强的阴影区。本文介绍了计算阴影区场强的两种方法,并与实测场强值进行了比较,证明计算值与实测值非常接近。
Due to the reflection of television waves by high-rise buildings, a shadow area of radio field strength is formed behind the buildings in the incoming direction. In this paper, two methods to calculate the field strength in the shadow area are introduced and compared with the measured field strength to prove that the calculated value is close to the measured value.
