应用数字工业摄影测量实现天线反射体姿态恢复

Application of Digital Industrial Photogrammetry to Realize Antenna Reflector Pose Recovery

介绍了天线在安装现场实现无塔标校的一种方法。根据公共点坐标转换原理,采用数字工业摄影测量(简称摄影测量)技术,实现天线反射体(包括主反射面、副反射面、馈源)姿态的恢复。通过天线反射体姿态恢复后所测试Ka/S波段方向图和测试Ka/S波段原始方向图比对,可知天线电性能指标恢复满足要求。

A method to calibrate the antenna without installation at the installation site is introduced. According to the principle of public coordinate conversion,by means of digital industrial photogrammetry（ referred to as photogrammetry） technology,which makes the attitude restoration of antenna reflector（ including main reflector、subreflector and feed） come true. Through the antenna reflector after pose recovery test Ka/S band diagram and test Ka/S band original pattern indicates the electrical properties of the antenna recovery meet the use requirements.
