摘要
针对目前超宽带雷达系统的带宽及数据量较大、采样率高、结构复杂等问题,文中设计了一套数字综合系统。该系统采用VPX标准架构进行高集成度的模块化、轻小型化设计。以Windows系统的计算机板卡为中控,各模块基于FPGA进行设计,分别实现超宽带信号产生、超宽带信号采集、高速大容量存储。实验结果表明,所提设计在6U 6槽机箱中实现了两个独立通道的3.6 GHz带宽基带信号产生与视频信号采集,以及24 TB容量、存储速度达3.1 GB/s的数据存储,为超宽带雷达系统的数字化设计提供了有效的解决方案。
Aiming at the problems of ultra⁃wideband radar system,such as wide bandwidth,high sampling rate,large amount of data and complex structure,a set of digital integrated system is designed.Adopt VPX standard architecture to carry out high integration,modularization,light and miniaturization design.The computer board card based on Windows system is used as the central control,and each module is designed based on FPGA to realize ultra⁃wideband signal generation,ultra⁃wideband signal acquisition,and high⁃speed large⁃capacity storage.The experimental results show that two independent channels of 3.6 GHz bandwidth baseband signal generation and video signal acquisition are realized in a 6U 6-slot VPX chassis,with a data storage capacity of 24 TB and a storage speed of 3.1 GB/s.It provides an effective solution for the digital design of ultra⁃wideband radar system.
