频域多通道UWB—SAR接收机结构分析

    Structure Analysis of Ultra-Wide Band Multi-channel SAR Receiver

      摘要
    • 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，给出了一种切实可行的临界采样频域分割方法。

       

      Abstract: 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.
