| 摘 要： | 介绍了天线偏移损耗,对天线自动对准原理进行了简要描述,通过对天线的粗对准及精确对准这2个环节的分析,确定天线粗对精度是保证天线自动对准成功的基础和关键,通过进一步对电子罗盘、角度传感器等设备精度及天线零位偏差分析,确定了天线粗对精度取决于天线零方位与于车体方位及天线零俯仰与水平面的偏差。为保证天线自动对准的可靠实用,提出了天线校准的方法步骤。

| Abstract: | The characteristics of scatter communication and antenna excursion loss are introduced.The principle of antenna auto alignment is described in brief.According to the analysis on antenna coarse alignment and perfect alighment,it is ensured that the coarse alignment is the linchpin of antenna alignment.After analyzing further the precision of electronic compass and angle sensor and the antenna zero azimuth error,the precision of antenna coarse alignment depends on the error between antenna zero azimuth and vehicle azimuth,and the error between antenna zero pitching and horizontal plane.In order to ensure reliable and practical antenna auto alignment,the antenna alignment method and steps are proposed. |
