摘要
瞄准线误差的测试是评价天线罩电气性能必不可少的环节。文中提出了一种自动电轴跟踪的快速寻零方法。通过自动控制发射天线在扫描架上水平移动,跟踪接收天线在天线罩影响下的波束指向偏转,并记录移动距离。利用文中提出的方法对天线罩瞄准线误差进行测试,结果显示,天线的扫描范围减小了77%,测试时间仅为传统方法的0.36倍。可以看出,文中提出的动态寻零方法可有效缩短发射天线的扫描范围,提高测试速度。
Measurement of boresight error（ BSE） is an essential step in assessing radome electrical property. A fast null-seeking method by automatic axial-tracking was represented in this paper. By this method,transmitting antenna lying on scanner was controlled automatically to move horizontally,tracking the beam shift of undertest receiving antenna influenced by radome automatically and recording the shift distance. The proposed dynamic null-seeking method was used to measure a radome BSE. The results show that the scanning distance decreases by 77% and the runtime is only 0. 36 times of that got by traditional method. It can be seen that the dynamic null-seeking method can shorten scanning range of transmitting antenna significantly and accelerate measuring speed.
