Design and research of a high speed and large capacity radar data storage system based on CompactPCI bus

伴随雷达宽带分辨率的不断提升,雷达系统对大容量数据存储和传输速度的需求更高。磁盘阵列技术的应用有效增加了雷达系统的数据存储容量,基于Compact PCI总线构架的雷达系统的数据存储速度显著提高,实现了雷达数据到服务器的高速传输和存储。据有关测试报告显示,基于Compact PCI总线构架的大容量雷达系统的数据存储速度已达到每秒156兆左右,符合当前雷达数据高分辨采集的存储需求。基于此,本文首先介绍了磁盘阵列技术,再对雷达系统总体架构设计进行简单说明,最后对Compact PCI接口设计进行深入研究。

With the continuous improvement of radar broadband resolution, the demand for large capacity data storage and transmission speed is higher. Application of disk array technique is effective in increasing the data storage capacity of the radar system, the data storage speed radar system based on CompactPCI bus architecture significantly improved, realize the radar data to the server of the high-speed transmission and storage. According to the test report shows that the data storage speed of large capacity radar system based on CompactPCI bus architecture has reached about 156 MB per second, in line with the current high resolution radar data acquisition storage requirements. Based on this, this paper first introduces the disk array technology, and then the overall architecture of the radar system design for a simple description,and finally the CompactPCI interface design in-depth study.
