摘要：

宽带侦察DBF的突出问题是高频段信号会出现严重的栅瓣。文中针对宽带DBF中栅瓣问题,提出了一种基于栅瓣等波动阵列方法,即阵元间距的选择随着宽带信号的频率变化而变化,其核心是对阵元间距的选则。并通过仿真验证了该方法的有效性。

关键词: 宽带DBF, 阵列设计, 栅瓣抑制

Abstract:

An outstanding problem of broadband reconnaissance DBF is the serious grating lobe at high frequency band of signal.This paper presents a digital array design based on grating lobe equiripple,that is,the selection of array elements spacing based on the change of the frequency of broadband signal,which proves effective by simulation.

Key words: broadband DBF;array design;grating lobe suppression
