新的作战对象和作战环境对现代雷达系统提出了新的挑战,需要具备同时多功能、复杂电磁环境对抗以及宽带成像和识别等能力。雷达系统数字化技术发展需要信号处理架构能够满足海量数据高速实时传输,并且运算节点可任意交换以及可重构能力。传输交换体系是构建大带宽、高密度计算实时处理系统关键技术。文中介绍了动态最短路径枚举路由技术,可实现基于RapidIO协议处理平台的全交换拓扑结构;提出了可提升传输带宽和平台并行处理能力的并发静态枚举路由技术,可实现处理平台的网状多链路并行全交换拓扑结构。
New war fighters and operational environments pose new challenges to modern radar systems and require the simultaneous multifunction, complex electromagnetic confrontation and broadband imaging and identification capabilities. The development of digital system of radar system needs the signal processing architecture to meet the high-speed real-time transmission of massive data, and the computing nodes can be exchanged freely and reconfigurable. Transmission switching system is to build large-bandwidth, high-density computing real-time processing system key technologies. In this paper, the dynamic shortest path enumeration routing technology is introduced, which can realize the full switching topology based on RapidIO protocol processing platform. A parallel static enumeration routing technology is proposed to improve the transmission bandwidth and platform parallel processing capabilities. Multi-link parallel full switching topology.
