摘　　要：针对当前SAR系统平台对实时性和稳定性要求的不断提高,构建了一种基于嵌入式实时操作系统Vx Works的SAR实时成像信号处理系统。与传统SAR信号处理系统相比,文中系统的处理方式具有高效、实时、多任务并行等处理优点。并结合雷达成像系统,论述了系统模块组成以及系统工作模式,以及基于Vx Works的实时多任务的SAR信号处理软件设计步骤。通过外场试验,对系统进行了验证,结果表明该系统具有较高的可靠性。A real-time imaging signal processing system of SAR based on embedded real-time operating system VxWorks with a PowerPC as the core is constructed. Compared with traditional SAR signal processing systems, the SAR system based on VxWorks has the advantages of high efficiency, real-time and multitask parallel processing. The composition of system modules and the working modes of the system are described in detail, and the software design steps of real-time multi-task SAR signal processing based on VxWorks are also introduced. Finally, the system is validated by outfield experiments, and the result shows that this system has high reliability.
