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 the resolution of the radar broadband, the radar system has a higher demand for storage and transmission of large-capacity data. The application of the disk array technology effectively increases the data storage capacity of the radar system. The data storage speed of the radar system based on the Compact PCI bus architecture is remarkably improved, and the radar data is transmitted and stored at high speed to the server. According to the test report, the data storage speed of the large-capacity radar system based on the Compact PCI bus architecture has reached about 156 trillion per second, which is in line with the storage requirements of the current high-resolution radar data acquisition. Based on this, this paper first introduces the disk array technology, and then a brief description of the overall architecture of the radar system design, and finally the Compact PCI interface design in-depth study.
