摘要

在大孔径宽扫描角情况下

利用窄带相控阵发射不出去宽带高分辨信号

本文经理论分析说明了这一点

在性能上是最优的.与时域采用抽头延迟线的FIR滤波器波束形成方法和频域DFT波束形成方法相比

文中方法简单

所需设备量少

易于工程实现.

Abstract

Theoretical analysis demonstrates that wideband signal can not be transmitted by using narrowband phased array in scenarios with large aperture and scan angle.Two wideband transmitting beamforming methods for phased radar based on the known waveform in the presence of large scan angle are proposed.The diagrams are given

and simulation results show the effectiveness of two methods.The novel methods employ digital processing in the time domain and are optimal.Compared with the beamforming method utilizing FIR filter consisting of tapped delay lines in the time domain and the beamforming technique with DFT in the frequency domain

the presented methods demand the smaller number of equipment and are easy to be implemented in engineering.
