摘　　要：基于开源式软件无线电平台GNU Radio设计软件化雷达中心机架构,实现相控阵搜跟一体雷达中心机的快速开发和组件可重构。介绍了中心机接口、任务组成和工作流程,通过多线程并行处理多任务提高系统实时性,通过时序控制及优化保证仿真准确性,采用Message实现各分机通信。半实物测试表明设计的中心机满足雷达仿真要求,且能复用和重构。A central computer system framework of software radar is designed based on GNU Radio,which is an open-source radio platform.This make it more quickly in radar design and development,and let the components of central computer can be reconfigured.Central computer processing time is reduced significantly by multi-thread.Simulation accuracy is ensured by optimizing and controlling program running sequence.And components of radar communicate by message mechanism.After hardware-in-the-loop simulation testing,it is found that the framework can simulate radar’s searching and tracking targets in real-time,meanwhile,the component can be reused and reconfigured.
