摘　　要：针对导引头信息处理机研制和调试的迫切需要,设计以TMS320DM642数字信号处理器(DSP)为核心处理器,基于高性能PC机和PCI总线的数字场景仿真系统。系统既可以输出由PC机仿真的数字场景,也可以输出由CCD摄像头采集后经过A/D转换的数字场景;还可以接收信息处理机传来的目标跟踪结果,然后在数字场景中叠加跟踪框评估跟踪效果。重点介绍该系统的工作原理、基本组成与详细设计。试验结果表明系统满足了实际应用的需要。With advances in image？guided weapons,it is quite necessary to develop a real？time digital scene simulator sys？tem to manufacture and debug the seeker information processing machine. Digital scene simulator system based on TMS320DM642,PC and PCI bus was designed. The system can output the digital scenes simulated by PC,or output the digital scenes collected by CCD camera and then generated through A/D conversion. It also can receive the tracking result from the in？formation processor,and then superpose the cross cursor on the digital scene to evaluate the tracking effect. The working princi？ple,basic composition and detailed design of the simulator system are introduced in this paper. The implementing methods of the system software and hardware are described in detail. The experimental results indicate that the system can meet the require？ments of practical applications.
