摘　　要：随着我国航空航天事业的飞速发展,无人机集群和卫星星座的出现给地面测控站提出了更高的要求。全空域多目标测控系统的建设提上日程。和其他波束形成方式相比,基于软件无线电的数字多波束形成技术在全空域测控系统中具有独特的优势,值得深入研究。介绍了全空域测控系统对波束形成设备的需求,进而提出了基于射频采样的波束形成模块的实现,并对共形球面阵数字波束形成技术进行了分析。实测结果验证了基于射频采样的数字波束形成方案的可行性。As the development of Chinese aeronautics and astronautics,the higher requirement is proposed to TTC ground station for the unmanned aerial vehicle swarming and satellite constellation. It is necessary to construct the whole airspace multiple-target TTC system. Compared with other beam forming technologies,the digital beam forming technology has some unique advantages. This paper introduces the demand of beam forming equipment in whole airspace TTC system. The implementation of beam forming module is put forward based on RF sampling. The conformal spherical digital beam forming technology is analyzed. The test results show that the digital beam forming scheme based on RF sampling is feasible.
