摘要
采用时域门测量方法研究分析了在开阔试验场上测量天线系数时,场地周围树木反射、天线塔反射、场地边缘散射对天线系数测量的影响,并针对树木的影响做了仿真,仿真结果与时域门测量法分析结果一致,说明了时域门测量法分析场地环境因素对天线系数测量影响的准确性。研究结果显示,场地周围树木反射以及天线塔发射对场地衰减的影响均接近0.5dB,而场地边缘散射的影响也达到0.3dB。最后,以测量结果为依据,提出相应的改进措施,提高测量精度。
Time domain measurement method was used to study the effect of the reflection of the trees, the reflection of the antenna tower and the plane-edge scattering when measuring the antenna factors on an OATS. And we also simulated the influence about the trees. Besides, the experimental result of the emulation was in accordance with that of time domain gating method, which confirms the accuracy of time domain gating method used for analyzing the effects of environmental factors on measuring antenna factor. The results show that the effect of the trees and the tower are both close to 0.5 dB,and the plane-edge scattering also reaches 0.3 dB approximately. At last,we can propose improvement steps and raising measurement accuracy according to the research results.
