| 针对地面测控系统中一些天线系统时延无法利用信标塔进行精确标定的缺点，提出了对天线系统时延进行分段计算和测量的标定方法，对标定精度进行了分析和计算，并分析了不同因素对天线系统时延变化的影响。工程实践证明该方法可行，天线系统时延标定精度优于0.1 ns。 |

| Abstract: |
| In ground segment of aircraft TT&C system,the time delay of some antenna systems can not be calibrated accurately by beacon tower.For this shortcoming,a calibration method is proposed in which antenna system is computed and measured segmentally.The calibration accuracy is analyzed and computed.The effect of different factor on the time delay variation of antenna system is analyzed.Engineering practices prove the feasibility of the proposed method. The calibration accuracy is better than 0.1 ns. |
| Key words: aircraft TT&C system ground segment antenna system equipment time delay(ETD) time delay calibration |
