摘　　要：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。According to the security shortcoming of current TT＆C system, the impulse radio UWB （ Ultrawideband） technology is introduced into the TT＆C system, and a new impulse radio UWB TT＆c system is established. On the basis of research on impulse radio UWB technology and its performance, the TT＆C signal model is built. Then, the system structure and working process of impulse radio UWB system are introduced and the signal parameter selection is discussed. At the same time, the implementation methods of range, range rate measurement and data transmission functions under the new system are researched. Regarding the analysis, it shows that the concealment and anti-interference performance of TT＆C system can be greatly imporved by deploying the impulse radio UWB TT＆C system, while range measuring precision is promoted. Thus, the requirement of emergency covert TT＆C system can be met.
