摘　　要：为了将地理信息系统(GIS)技术与态势信息情报很好的融合,提出一种基于ArcGIS的高性能实时态势显控系统,利用插件式、模块化的统一架构来提高系统可扩展性。同时针对大量目标数据处理及显示的实时性问题,结合近年来硬件与GIS技术发展趋势,提出采用统一调度的多线程并行数据处理、GPU硬件加速以及符号与数据缓存等机制达到提高系统数据吞吐量与显示性能的目的。实践结果表明,该系统具有良好的可扩展性和实时性。To integrate GIS technology into situation information and intelligence, a high performance real-time situation display-control system based on ArcGIS is proposed. A plug-in, modular architecture is designed to improve system scalability. Aimed at the real-time problems of handling and displaying mass target data, based on current trends in hardware and GIS technology development, multi- threaded parallel data processing using unified dispatch, GPU hardware acceleration, as well as symbols and data caching are proposed to improve system performance. Results of the practice indicated the proposed system has good scalability and real-time performance.
