摘　　要：为了挖掘船载X频段测控雷达的设备潜能,解决船摇情况下X频段卫星信号的窄波束角度捕获的难题,提出了利用船载X频段测控雷达跟踪S频段接收信号进行自引导的设计方案。对S/X双频馈源进行测试,并在X频段下行链路分析的基础上进行S频段链路的设计,设计出满足系统G/T值的下行链路配置,通过跟踪风云气象卫星进行功能验证和跟踪精度分析,证明该设计方案技术可行,满足指标。To advance the ability of shipboard X band tracking telemetering&control(TT&C)system,the scheme was proposed,which can capture and track the signal of S-band for self-guiding.It can also solve the key technical problems for the narrow beam antenna capture on the X-band signal in ship-sway environment.Dual-band feed was tested,which works in S/X dual frequency band.Based on a detailed analysis of the X Band-downlink requirements,the scheme of the S band-downlink was given,which can meet the G/T value of shipboard S band TT&C system.It's function was validated by tracking the FY-3B satellites.The precision analysis indicates that the scheme satisfies requirements.
