摘　　要：以凌华科技的DAQStreaming系统为例,详细地论述了PXI平台在航空遥感数据记录系统中的应用前景。通过对系统体系结构的深入分析,指出了限制系统记录速度提高的瓶颈所在,结合最新发展的PCIExpress总线技术和SATA硬盘存储技术,提出了一套基于PXIe平台和SATA磁盘阵列的高速数据记录方案,实现了记录速度的成倍提高。Taking the DAQStreaming system of ADLINK Technology Inc. as an example, the application prospect of PXI platform in the data recording system for airborne remote sensing devices is discussed in detail. By an in-depth analysis of the system architecture, the bottle-neck that limits the improvement of the recording speed is identified. By introducing the new arising PCI Express technology and SATA hard disk storage technology, a new high-speed data recording scheme based on PXIe platform and SATA disk array is suggested, which can double the recording speed.
