摘要
针对宽带相控阵雷达海量数据传输和数字多波束形成计算量大的需求,提出了基于任意时延滤波器的宽带数字波束形成算法,设计实现了一种基于该算法的高速多通道宽带数字波束形成器。该DBF采用高速串行接口、FPGA并行计算和模块化程序结构的设计思路,具有传输带宽大和实时性强的特点。测试结果表明:设计的DBF作为宽带数字多波束形成工程应用的初步探索,具有良好的性能。
For the requirement of great amount of transmission and calculation to form multiple-beam simultaneously for phased array radar (PAR),a new wideband digital beamforming algorithm is presented based on random delay filters,upon which a highspeed,multi-channel wideband digital beamformer (DBF) is designed and realized.The DBF adopts the high serial interface,parallel calculation of filed programmable gate array (FPGA) and modularized program,which leads to high bandwidth and strong real-time property.Experiments show that the DBF designed as an elementary investigation has good performance.
