一种动态调制滤波器组高效结构设计
Design of an efficient structure for dynamic modulated filter banks
摘要
Abstract
The bandwidth of the pulse compression radar signal becomes wider in electronic reconnaissance field,therefore it is required that the electronic reconnaissance receiver should have the wider instantaneous bandwidth,which may reduce the sensitivity of the receiver. Aiming at this problem,an efficient structure design method of the dynamic modulated filter banks is proposed. By analyzing the signal accurate reconstruction conditions,the iterative algorithm is used to design the prototype low-pass filter of the dynamic modulated filter banks,and an efficient structure of the dynamic modulated filter banks is constructed. The computer simulation result shows that the efficient structure of the dynamic modulated filter banks can reconstruct the origi-nal signal accurately. The efficient structure can reduce the computation quantity,and improve the sensitivity of the receiver.关键词
