摘要: 随着现代高分辨雷达带宽的不断提高,雷达系统对大批量数据传输和存储速度有了更高的要求。采用光纤通道磁盘阵列实现大容量雷达数据的存储,通过设计高速CompactPCI总线接口实现雷达数据到主机的数据传输,利用CompactPCI平台实现了大容量数据的高速存储。设计的存储系统实际测试存储速度达到155.6 MB/s,已能满足目前大部分高分辨雷达宽带数据去斜采集的存储要求。

Abstract: With the development of high-resolution radar,radars bandwidth becomes more and more broad and radar system has a higher demand of data transmission and storage speed.Through using RAID(Redundant Array of Independent Disks) of fibre channel to reserve large capacity radar data and designing high-speed CompactPCI bus interface to realize the transmission of radar data to host computer,a high-speed storage system of large capacity data has been realized based on CompactPCI bus platform.The storage speed of designed system achieves 155.6 MB/s in actual test,and can satisfy the demand of most high-resolution radar data storage of dechirping sampling.
