摘　　要：以全数字化信号产生和数字波束形成处理为基础的数字化阵列雷达已成为当代相控阵雷达技术发展的一个重要趋势,本文针对现代数字化阵列雷达对多通道数据采集和实时处理的需求,设计了一种基于FPGA的多通道实时阵列信号处理系统。可完成对20通道的中频数据采集,实时波束合成和数据传输功能,实验结果表明系统工作稳定、性能良好,具有良好的信噪比和通道一致性。Digital array radar which based on all-digital signal generation and digital beam forming process has become an important trend in phased array radar technology. For the demand of modern digital array radar in multi-channel data acquisition and real-time processing, designed a FPGA real-time multi-channel array signal processing-based systems. Completed on 20 channels IF data acquisition, real-time digital beamformer and data transmission. Experimental results show that the system is stable, good performance, with good signal to noise ratio and channel consistency.
