摘　　要：宽带发射波束零陷展宽算法分为频域处理和时域处理两大类别。论文取采用频域处理方式,对阵列发射的宽带信号进行FFT处理,并构建聚焦矩阵,再分别对各个频率的信号进行窄带零陷展宽处理,即可在置零方向上形成宽零陷。Thewideband transmitting null beamforming algorithm is divided into two categories,which are frequency domain processing and time domain processing. In this dissertation,the frequency domain processing method is used,the fast Fourier transform(FFT)process is used to wideband signal transmitting by the array,and the focus matrix is constructed,and then the narrowband transmitting null beamforming is performed on the signals of each frequency,which canform null broadening in the known null direction.
