RTLinux在雷达信号采集处理系统的应用

Design of radar signal acquisition and processing system based on RTLinux

介绍了RTLinux的结构特点,提出对某雷达信号采集处理系统改进的设计方案,分析了雷达信号采集处理系统的软硬件组成。重点研究了RTLinux对该系统的实时模块的任务控制方法。并给出了非实时任务的实现结果,在RTLinux下对中断响应时间进行了实时性能测试。结果表明,RTLinux具有好的实时性能,新系统的实时和稳定等性能得以提高。

The structural characteristics of RTLinux are introduced. Then a design scheme is put forward for improving the signal acquisition and processing system for a certain type of radar. The software and hardware of the system are analyzed,with focus on task control method of the RTLinux for the real - time models. The realization result of the non real - time tasks is given. We took a real - time performance test for the interrupt response time of the system by using RTLinux. The result proved that RTLinux has good real - time performance, the stabilization and the real - time performance of the new signal acquisition and processing system are improved.
