The Influence Research of Stability of the Launcher on Outdoor Antenna Far-field Test Results

采用matlab软件,分析在室外条件下,发射塔稳定性对高架天线远场测试的影响。高架天线发射塔在风力作用下产生摆动时,引起接收天线接收到的电磁波信号具有相位误差,从而影响天线远场测试结果。为分析上述问题,以一维直线阵为例并结合天线阵列综合技术,分析相位误差对天线性能指标测试的影响,并给出天线测试精度对发射塔稳定性要求。通过此项研究,对所需测试精度设计适当的发射塔工艺和结构有一定的指导作用。

In this paper, the matlab software is used to analysis the stability of the launcher influence on outdoor antenna far-field test results. The launcher swing due to the wind power, thus the elevated antenna receives the microwave signal with phase error, as well as influence the performance of testing results. For analysis above phenomenon, a linear antenna array combine with synthesis technology is adopted, in addition the test precision requirement for stability of the launcher is presented. It can provide guideline to design the process and structure of the launcher according to the required test accuracy.
