| 摘要: |
| 针对大部分航天测控站下行链路校相功能还依赖标校塔的现状，分析了偏馈模式和有线模式下方位、俯仰误差电压比例值保持稳定的原理，提出了利用该稳定性实现测控站无塔校相的方法。实验证明，利用该方法得到的校相结果交叉耦合小于七分之一，定向灵敏度满足要求。该方法解决了设备组合变更或设备检修后需要重新标定的问题，可应用于双通道跟踪体制的统一测控系统，具有很强的实用性。 |

| Abstract: |
| According to the situation that most down-link phase calibration methods of space tracking station need calibration tower,this paper analyzes the theory of error voltage ratio keeping stability under offset-feed mode and radio frequency(RF) loop mode.A towerless phase calibration method based on this stability is proposed.Experiments prove that in the phase calibration results through this method,the cross-coupling is less than 1/7 and the directional sensitivity meets the requirement.The method solves phase calibration problem after device combination changing or device maintenance and can be applied in the unified Tracking Telemetry and Command(TT&C) system adopting dual-channel tracking mode.This method has very strong practicability. |
| Key words: unified TT&C system dual-channel tracking system towerless phase calibration error voltage ratio |
