摘要:
基于超宽带采集存储技术构建了测量与监视系统,实现了对无线电监测系统试验场中的模拟无线电监测目标信号群的测量与监视。重点研究了基于并行交替采样的超宽带信号高速采集技术、基于固态磁盘(Solid-State Disk,SSD)阵列流水拼接的海量数据实时存储技术和基于统一计算设备架构(Compute Unified Device Architecture,CUDA)的超宽带信号频谱分析技术等关键技术。测量与监视系统工作频率范围为1.5 MHz~22 GHz,单通道采集速率可达5 GB/s,三通道实时带宽达到6 GHz,最大存储容量达到48 TB,满足对无线电监测系统试验场中通信、导航、雷达等多路模拟无线电监测目标信号进行测量与监视的使用需求。

Abstract:
A measurement and surveillance system based on ultra-wideband(UWB) acquisition and storage technology is constructed to measure and surveille the simulative radio monitoring target signal group in the test field of radio monitoring system.The key technologies are studied specially,including UWB signal acquisition based on parallel alternating sampling,mass data real-time storage technology based on solid-state disk(SSD) array pipelining split join and UWB signal spectrum analysis based on compute unified device architecture(CUDA) technology.The frequency of the monitoring system ranges 1.5 MHz to 22 GHz,the single channel acquisition rate can reach 5 GB/s,the three-channel real-time bandwidth reaches 6 GHz and the maximum storage reaches 48 TB.It can meet the requirements of monitoring and measuring communication,navigation,radar and other simulated target signals in the test field of radio monitoring system.
Key words:  ultra-wideband(UWB)  radio monitoring  efficiency evaluation  parallel alternating sampling  mass data storage
