三轴天线角度标校方法

三轴天线角度标校方法

内容简介：三轴天线系统主要用于对低轨卫星的全空域无盲区跟踪。对于斜转台三轴天线系统，已有的方位-俯仰座架的误差模型及标校方法已不适用。依据三轴天线系统的特点，分析研究了三轴天线系统的各项误差，提出了三轴天线系统误差修正的数学模型和标校的具体方法，并结合三轴天线实测数据进行了试验验证。该标校方法已应用于实际工程中，取得了良好的效果。

Abstract：Tri-axis antenna system is mainly used to track the low earth orbit satellites in the whole airspace without blind zone. The existing error model and calibration method of azimuth-elevation pedestal are not suitable for tri-axis antenna system with tilt turntable. Based on the characteristics of the tri-axis antenna system,the errors of tri-axis antenna system are analyzed, and a mathematical model of error correction and some calibration methods for tri-axis antenna system are presented in this pa-per. The tri-axis antenna system was verified in combination with its detected data in experiment. The calibration method has been used in practical engineering,and good results have been achieved.
