| 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. |
