基于VxWorks的末制导雷达通用信号处理平台设计

Design of General Terminal Radar Signal Processing Platform Based on VxWorks

通用的雷达信号处理平台在中断响应、数据传输等方面对系统的实时性和可靠性要求较高,在设计时有必要采用高性能的实时操作系统,同时采用PCI总线来保证高速的数据传输。为此,基于实时操作系统VxWorks,以高性能微处理器PowerPC7457为核心,采用PCI总线机制,借鉴软件模块化思想,构建了通用的雷达信号处理平台。可用于信号处理算法的开发验证,具有较高的实时性和扩展性。

In general radar processing platform, due to the high demand to realtimeness and reliability in terms of interuptting response and data transmission,it is necessary to select high performance real-time operating system and PCI bus to guarantee high speed data transferring.For this, the platform kernel with microprocessor PowerPC7457 is designed by using, real-time operating system VxWorks, PCI bus mechanism, the idea of the soft module.This general signal processing platform can be used to produce signal processing algorithm,the result indicate sthat this platform has high realtimeness and extendibility.
