An ultrafast digital signal processor for millimeter wave real-time imaging radar

The millimeter wave real-time imaging radar has the capabilities of high range resolution and Doppler resolution, which puts forward a new challenge for digital signal processor. Based on the analysis of technical characteristic of real-time imaging radar, a new kind of digital signal processor structure is presented. The processor adopts multi DSPs and multi FPGAs structure. And the design methods of ultrafast interconnection among different chips are presented in detail. This architecture is based on high-speed interconnect platform, having several kinds of interconnection methods which are Serial RapidIO net, PCIE net, HyperLink net and synchronization timing bus. So it meets the demand of the great data throughput for real-time imaging. The software structure is introduced based on AXI-Stream protocol. The digital signal processor has a good characteristic of modularization, scalability and universality.
