| 摘要: |
| 在空间预警系统中，为了降低系统预警精度受视线测量系统误差的影响，必须对仪器进行定标，因此需要深入对视线误差进行讨论。本文在对视线误差深入研究的基础上，从理论上讨论了视线误差对发射点、射向、落点估计结果的影响，得出系统误差变化率是影响预警结果的重要因素之一，并针对常值系统误差、线性系统误差以及周期系统误差进行了相应的预警仿真计算，从而为几何定标方案的确定提供支持。 |

| Abstract: |
| In order to reduce influence on early warning results caused by the system error in the early warning system, the calibration to the instrument must be carried on. So it is necessary to discuss the line of sight measuring error farther. This article theoretically discussed the sight error influence on early warning results, including trajectory launch point, trajectory course, and trajectory falling point, and found that the most important influence factor was frequency change. Based on the constant error, linearity error and periodicity error, the corresponding simulation was given to provide the support for the geometry calibration plan. |
