摘要
探讨了应用于雷达电子战系统的宽带数字波束形成(DBF)技术。提出了一种恒定束宽的宽带数字波束形成新方法,该方法将均匀线阵视为连续线阵的均匀离散采样,将空间重采样思想用到恒定束宽波束形成器设计中。仿真结果证明了该方法是正确、有效的。
The application Digital Beamforming(DBF) to wide band radar EW system is introduced.And the constant beamwidth digital beamforming method is proposed.The uniform linear array is regarded to be the discrete sampling of the continuous array,and then the idea of spatial resampling is used here to design the constant beamwidth beamformer.The computer simulation results show that the method is correct and effective.
