摘　　要：分析了一种基于频域多通道的超宽带合成孔径雷达 (UWB SAR)接收机结构。比较了各种滤波器原型在频域分割滤波器组中的性能 ,依据正交镜像滤波器组 (QMF)原理 。In this paper, the structure of an Ultra-WideBand SAR receiver based on multi-channel in frequency domain is analyzed. The performance of prototype filter in the division filter banks is discussed. Based on the theory of Quadrature Mirror Filter Banks (QMF), A feasible design method of a Critically Sampled filter banks is presented.
