统一测控系统新一代综合基带设计研究

Design Research of a New Generation of Integrated Baseband Technology for Microwave Unified TT&C System

近年来,我国微波统一测控系统取得了长足进步,但现有测控综合基带面对测控任务的逐步密集、测控系统的日益庞大以及测控技术的不断发展,在系统和应用层面暴露了较多技术短板。因此,在对比分析同类技术发展趋势和设计需求的基础上,提出了以前端射频信号数字化、后端基带处理虚拟化为基础,以云计算架构和资源"池化"技术为核心的新一代综合基带体系架构,以及在设计实现中应重点研究的宽带射频信号采集、海量数字信号I/O、零中频接收架构、信号处理硬件加速等关键技术,以期推动统一测控系统综合基带技术发展。

In recent years,the unified microwave TT&C(Tracking,Telemetry and Command)system has made a great progress in our country.However,facing the development of TT&C technology,the increasing number of TT&C mission,and the complexity of TT&C system,the existing integrated baseband has shown disadvantages in system design and daily practice.Therefore,according to the research on the development trend of the similar techniques and the design requirements,a new generation of integrated baseband system architecture is proposed based on the front-end RF signal digitalization and the back-end baseband processing virtualization.The new architecture is realized chiefly by use of cloud computing architecture,virtual technology,and resource pooling technology.The research emphasis are paid on the key technologies including wide-band RF signal sampling,massive digital signals I/O,zero-IF receiving technique,and hardware-accelerated signal processing.In view of the above,this paper looks forward to the promotion of the baseband technologies in unified microwave TT&C system.
