摘要
随着航空、雷达、声纳、遥感卫星图像传输等领域实时数据采集量的不断增加,以及实时数据处理系统能力的不断提升,对记录和回放系统的数据传输速率提出了更高的要求。现提出了一种高速雷达数据回放系统的实现方案。采用高性能的磁盘阵列和I/O控制载板,同时结合定制化设计的零延时换序PMC卡,使得单通道数据回放速率可以达到512Mb/s,满足了系统的设计指标。
The amount of real time data collection is increasing rapidly in the fields of aviation, radar, and sonar, satellite image transmission. And the same time, the ability of real time data processing is also improving promptly. These changes mean that the recorder and the playback system need the stronger ability of processing mass - data. This article introduces an available scheme of high speed radar＇ s playback system. With using the high performance disk - group and I/O controller carrier, and the zero delay format converting PMC card, the playback data rate of single channel can reach 512Mb/s and meet the require of the system design.
