提高精密跟踪雷达测量精度的重要环节是对系统误差进行修正。修正所需的雷达机械误差数据过去是用预先设置的校准塔和方位标来校准的。这种方法所需设备较多且有一定局限性,尤其不适用于机动式雷达站。本文给出一种以恒星为基准的校准方法,这种方法不需要上述设备,仍有足够的精度,因而是一种比较好的校准手段 An important part of improving the accuracy of the precision tracking radar is to correct the system error. Radar mechanical error data required for calibration were previously calibrated using pre-set calibration towers and bearings. This method requires more equipment and has some limitations, especially not suitable for mobile radar stations. This article presents a star-based calibration method that does not require the above equipment and still has sufficient accuracy and is therefore a good calibration
