| 摘要: |
| 随着在轨航天器数量向着千颗量级发展，传统测控系统“一对一”测控方式已经难以适应未来大规模在轨航天器测控管理任务。为适应航天领域的发展需求，全空域多目标测控系统应运而生。全空域多目标测控系统是球面相控阵技术与数字多波束合成技术在测控系统中的首次应用，具备空间多个目标同时测控的能力。首先，介绍了全空域多目标测控系统的基本结构和原理；其次，综述了全空域多目标测控系统国内外研究现状、应用及实现的关键技术；最后，指出了全空域多目标测控系统存在的主要问题及未来的主要研究方向，可为多目标测控系统的后续研究提供参考。 |

| Abstract: |
| As the number of spacecraft in orbit grows toward thousand level，the “one-to-one”measurement and control method of the typical TT&C system has been difficult to meet the control and management tasks of the large scale on-orbit spacecrafts in the future.In order to meet the development needs of aerospace technology,the hemispherical coverage multi-target TT&C system came into being.In hemispherical coverage multi-target TT&C system,spherical phased array technology and digital multi-beam forming technology are applied firstly,which is able to measure and control multiple targets simultaneously in space.Firstly,the basic structure and principle of hemispherical coverage multi-target TT&C system are introduced.Secondly,the domestic and foreign research status,application and key technologies of the hemispherical coverage multi-target TT&C system are summarized.Finally,the main problems and future research directions of the hemispherical coverage multi-target TT&C system are pointed out，which can provide theoretical reference for the follow-up research of multi-target TT&C system. |
