摘要
Abstract
Conventional depends on compensating phase⁃shift resulting from time delay between array elements. For wide⁃band digital array,the same time delay and different frequency bring different phase shift. The narrowband digital array beam⁃forming method results in beam pattern deviation and main lobe distortion in broadband beamforming. Through the analysis of im⁃pacts of signal bandwidth on narrowband digital beamforming and the principles of wideband digital beamforming,the paper in⁃troduces the broadband beamforming method based on fractional delay. The analysis and simulation results show that the method is effective for broadband beamforming.关键词
