针对当前航天测控系统安全性不足的问题,将脉冲超宽带技术引入到测控系统中,构建脉冲超宽带测控体制。在对脉冲超宽带技术及其性能进行研究的基础上,建立了测控信号模型。介绍了脉冲超宽带测控系统的构成与工作过程,并探讨了信号参数的选取。同时研究了新体制下测距测速和数据传输等功能的实现方法。分析表明,脉冲超宽带测控体制可大大提高测控系统的隐蔽性和抗干扰能力,同时提高测距精度,满足应急隐蔽测控的需求。
Aiming at the problem of lack of safety in the space flight control system, the pulse ultra-wideband technology is introduced into the measurement and control system to build the pulse ultra-wideband measurement and control system. Based on the research of pulsed ultra-wideband technology and its performance, the measurement and control signal model is established. Introduced the pulse UWB measurement and control system of the composition and working process, and discusses the selection of signal parameters. At the same time, it also studies how to realize the functions of ranging speed measurement and data transmission under the new system. The analysis shows that the pulse UWB measurement and control system can greatly improve the concealment and anti-interference ability of the measurement and control system, meanwhile improve the accuracy of ranging and meet the requirements of emergency hidden measurement and control.
