摘要
本文分析了干扰信号带宽、通道幅相误差以及Ａ／Ｄ变换器的量化噪声等对数字波束形成的干扰对消效果的影响，给出了由于这些因素产生的剩余干扰功率的解析表达式及数值计算结果．
In this paper, the effect of the bandwidth of interference, qualitization noise of A/D converters and errors of amplitude and phase in channels on the performance of cancelling interference in Digital Beamforming is analyzed.The analytic expressions about residual power of the interference which is caused by the factors mentioned above are presented.Some numerical results are also provided.
