Beamfoming Methods in Time Domain for Wideband Digital Array with Large Aperture

LI Tao;WANG Xuegang;ZHOU Yun;YU Xuelian;School of Electronic Engineering,University of Electronic Science and Technology of China;  
It has been successfully applied to the receiving beamforming of wideband digital array radar( WDAR) using stretch processing to linear frequency modulation( LFM) signal. However,it is still difficult to realize transmitting and receiving digital beamforming( DBF) of any type of wideband radar signal under the condition of large array aperture. According to the characteristics of WDAR and the development of digital signal processors at present,and by analyzing the array processing errors,two wideband DBF methods in time-domain based on digital phase shifting and digital delay are presented after comprehensively considering the realization complexity in engineering and performance of method. The two methods both have relatively good engineering feasibility and can effectively overcome the aperture effect to achieve transmitting and receiving DBF of any wideband pulse radar signal. The effectiveness of the methods is verified by computer simulation and some factors that have a major impact on the performance of the methods are also discussed.
