摘　　要：在深空测控系统的实际应用中,由于其天线口径大等原因,面临着角跟踪系统和差通道相位一致性需要在无塔条件下校准的关键技术难题。基于利用射电星校相的解决思路,首先通过分析确定了设计实现方案,并针对射电星信号的特点,结合具体的设计实现对其进行了理论分析,最后给出了实验验证结果。实验证明了射电星校相的可行性,这将对深空测控系统的应用具有非常重要的指导意义。In deep space TT＆C system, due to its large antenna, how to calibrate the phase difference between the sum channel and the difference channel will be a key technology in towerless condition in the angle tracking system. In order to solve this problem with radio star, a design scheme is proposed through analysis. According to the features of radio star signal, theoretical analysis is made and experimental result is provided. The feasibility of calibration with radio star is verified, which has instructive meaning for the application of deep space TT＆C system.
