| 摘 要： | 提出了一种以地球同步轨道卫星作为参考物、利用GPS位置对Ku波段地面及机载定向天线进行快速标定的方法；研究了将地心大地坐标变换到地心空间直角坐标参数和将地心空间直角坐标变换到站心极坐标的计算方法；给出了定向天线的标定实施步骤。测试结果表明，地面定向天线标定角度误差可达0.1°，机载定向天线标定角度误差可达1°，该标定精度可以满足大部分应用需求。

| Abstract: | With the help of the earth synchronous orbit satellite as a reference, a fast and precise method of adopting the GPS to calibrate the Ku band airborne and ground directive antenna is presented. The calculation method of the geocentric geodetic coordinate system to the geocentric space rectangular coordinate system is given. The calibration and implementation steps of directional antenna are given. The measure results show that the angle error of the grand directional antenna can reach 0.1°, and the angle error of the airborne directional antenna can reach 1°.The calibration accuracy meets most of the application requirements. |
