摘　　要：提出了把抢占式实时多任务操作系统 Vx Works引入到雷达系统 ,特别是多功能相控阵雷达中的必要性 ;分析了 Vx Works操作系统的优点 ;针对其图形功能弱的缺点和现有雷达显示系统的硬件条件 ,作者提出了在Vx Works操作系统下实现高分辨率光栅图形显示的方法及具体的实现过程。此方法适用性广 ,能应用于以Tms340 10 (或 Tm s340 2 0 )图形芯片为核心的任何雷达系统。The paper presents VxWorks, a preemptive real-time multitask operating system(RTOS) applied in radar system, especially emphasizes the essential of the application of VxWorks operating system in multifunctional phased anay radar. It analyzes the good qualities of the VxWorks operating system; pointed to VxWorks's shortcoming in graphics processing and existing hardware condition of radar display system, this paper points out the technique and its detailed implementation of high resolution raster graphics display in VxWorks operating system. This method can be widely used in any radar system whose graphics board CPU based on TMS34010 or TMS34020.
