| Abstract: | 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. |
