摘　　要：更高精度、更为可靠、更加智能以及同时服务更多目标将是统一测控系统未来追逐的目标,射频数字化技术的发展应用为实现上述目标提供了解决方案。测控系统射频数字化面临多通道不同步导致的测距零值晃动、测控数据时延抖动大等问题,提出了一种实用化的多通道同步与确定性延时处理方法。试验数据表明,数据时延抖动控制在0.02μs量级,系统测距零值稳定性提升60%(RMS 0.48 m),试验结果验证了该方案的有效性。Some goals are pursued by the unified Tracking,Telemetry and Command(TTC) system in the future,which include higher accuracy,more reliability,more intelligence and serving more targets at the same time.The development and application of RF digital technology provides solutions to achieve the above goals.The RF digitization of TTC system is faced with some problems caused by multi-channel asynchronization,such as ranging zero jitter and large delay jitter of TTC data.In this view,this paper proposes a multi-channel synchronous and deterministic delay method for solving these problems.The test data show that the data delay jitter is controlled in the order of 0.02 μs,and the zero value stability of the system ranging improves by 60%(RMS 0.48 m).These test results verify the effectiveness of the scheme.
