摘　　要：多波束测控系统可以同时完成多个目标的跟踪测量,但由于测站测控设备集中,其天线尺寸、发射功率大小不一,跟踪时出现相互干扰,导致多目标测控系统某一目标测量支路锁定异常。通过对多波束测控系统进行测试和试验,对系统EIRP一致性及变化进行测试,同时分析了测控链路的电平,根据分析结果制定在设备集中条件下目标捕获的策略。通过跟踪验证,未出现过锁定异常现象,可以实现稳定跟踪。结果表明,该方法能够满足多套设备集中情况下的跟踪要求,对后续设备设计具有指导意义。A multi-beam TT&C system can simultaneously perform the tracking and measurement of multiple targets.However,due to the concentration of TT&C equipment in TT&C station as well as the variety of antenna size and transmitting power,mutual interference occurs in the tracking process,which may result in the abnormal locking of a target measurement branch of the multi-target TT&C system.In this paper,the consistency and variation of EIRP of multi-beam TT&C system are tested,and the level of the TT&C link is also analyzed.According to the analysis results,the target acquisition strategy under the condition of equipment concentration is established.Tracking verification demonstrates that no abnormal locking occurs and stable tracking can be achieved.The results show that this method can meet the tracking requirements when multiple sets of equipment are concentrated,and it provides a guidance for subsequent equipment design.
