天线远场反射会对天线测试有一定的影响。首先介绍了使用喇叭进行增益测试来判断天线远场反射的方法；然后根据电波传播的菲涅尔区理论，在天线测试远场的发射端和接收端进行削波，以避免电磁波照射到地面形成反射和减少接收反射信号，从而达到消除反射的目的。并在一个远场作了验证，结果证实方法可行。

Antenna far-field′s reflection has definite influence on antenna testing. The method to judge far-field′s reflection by gain testing with a pyramidal horn is introduced in this paper. According to the Fresnel zone theory of radio wave propaga-tion,the clipping is done at both the transmitting terminal and receiving terminal of antenna testing far-field to avoid the reflec-tion that the electromagnetic wave irradiates on the ground and to reduce the received reflection signal,so as to realize the re-flection elimination. The feasibility was validated in a far-field experiment.
