在现有的机载环境下,对空中复杂环境的电磁信号的采集记录信息量巨大,往往无法在一次的飞行试验中实时分析所获取的信息。大容量实时信息采集存储的必要性越来越得到重视,在复杂环境中,各个波段的信号混叠预处理之后的数据需要在地面恢复重演。介绍了一种基于COM-E模块+Xilinx K7系列FPGA+RAID控制器+XMC存储模块架构的存储系统,模块化的设计更容易维护和日后升级使用。通过RAID-5的阵列管理方式灵活控制工作模式,提高存储速率。系统的实时写入带宽大于3GB/s,可以作为机载环境下采集设备后端的高速存储设备广泛应用。
Under the existing airborne environment, the huge amount of information recorded in the electromagnetic signals of the complex environment in the sky can not be analyzed in real time in a flight test. The necessity of large-capacity real-time information acquisition and storage is getting more and more attention. In complicated environment, the data after the signal aliasing preprocessing of each band needs to be repeated on the ground. This paper introduces a storage system based on COM-E module + Xilinx K7 series FPGA + RAID controller + XMC storage module architecture. The modular design is easier to maintain and upgrade in the future. Through the RAID-5 array management flexibility to control mode of operation, improve storage speed. The real-time write bandwidth of the system is more than 3GB / s, which can be widely used as a high-speed storage device at the back end of the acquisition device in the airborne environment.
