摘　　要：理想导体表面能够对电磁波信号进行几乎无损的全反射。智能反射面正是依据该原理实现对基站天线发射的电磁波信号进行全反射,从而达到使其能够绕到障碍物的侧面和背面进行覆盖的目的。智能反射面实现了对信号的拐弯覆盖,适合解决小面积的盲点区域覆盖,相对于新建站建设(包括微站)来说,其成本更低、实现更简单,是目前针对小面积较难覆盖盲区的理想化解决方案,但是如何定量地确定智能反射面覆盖的强度和区域覆盖面积的大小,还要更深入的研究和实验。本研究根据电磁波的入射角度,智能反射面的面积和基站天线的挂高差等参数进行理论计算分析,确定出覆盖目标面积和以上参数之间的函数关系。同时在外场试点搭建智能反射面覆盖模型,通过现场实测效果来验证该函数关系的有效性。The ideal conductor surface can fully reflect the electromagnetic wave signal.Intelligent reflector is made according to this principle that can realize total reflection of the electromagnetic wave signal transmitted by the base station antenna.So the intelligent reflector can realize the purpose of covering around the side and back of the obstacle.Intelligent reflector is more suitable for solving the problem of small area non-signal coverage.Compared with building a new base station,intelligent reflector is a more ideal solution that whose cost is lower and Implementation is easier.Hower,the current difficulties are how to quantitatively determine the size of coverage area.By studying the relationship between the three parameters that are the incidence angle and the area of the intelligent reflector and height difference of antenna,the functional relationship between the area of the covered target and the above parameters is determined.An experimental model built in the outfield is used to verify the effectiveness of the relationship.
