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 challenges are raised to new opposed object, new combat environment of modern radar system. So the radar system should achieve simultaneous multi-function capability, countermine ability in complex electromagnetic environment and the ability of wideband imaging and identification. With the development of digital technology in radar system, mass data should be transferred in high speed in signal processing architecture. The computational nodes can be exchanged between each other freely. And also the architecture should be reconfigurable. Transmission and Exchange system is the key technology in building real-time processing systems based on wideband and high density computing. A dynamic routing enum algorithm to choose the shortest path is introduced. And it can be used in the network topology for complete exchange system based on RapidIO protocol. To solve the problem in the mesh and multipath network topology for complete exchange system, a concurrent static routing algorithm is proposed in this paper. Thus, the transmission performance and the ability of parallel processing of the system are improved.
