摘要
针对当前密集复杂的电磁环境下雷达信号分选实时性与有效性问题,介绍了一种雷达信号分选系统设计。该系统基于实时操作系统VxWorks与高性能PowerPC处理器的组合平台,并采用了一种密集电磁环境下的自适应信号分选算法。通过合理分配任务结合相适应的任务间和CPU间通信方式,使得整个算法流程能够在四片PowerPC上有序高效地运行,从而在平台与算法两方面保证雷达信号分选的实时性与有效性。
In view of the real-time and effectiveness problems of radar signal sorting under the dense and complex electromagnetic environment,a radar signal sorting system is designed. Based on the combined platform of the VxWorks real-time operating system and the PowerPC high-performance processor,the system adopts an adaptive signal sorting algorithm in the high-electromagnetic-density environment. Reasonable task allocation combined with the suitable communication modes between the tasks and the CPUs is used to make the whole process of the algorithm run orderly and efficiently on four Power PCs. Therefore,the real-time performance and effectiveness of radar signal sorting are achieved in both the platform and the algorithm.
