摘要
Abstract
Broadband digital down⁃converter(DDC)and resample processing can be applied in the design of new wideband digital receiver in the fields of imaging radar and broadband reconnaissance in electronic countermeasure. The efficient realiza⁃tion way of resample filtering processing and broadband DDC based on polyphase filtering structure are discussed in this paper. A design instance is adopted to perform Matlab simulation and FPGA implementation. The simulation and implementation results are provided. This method can be used in the design of broadband digital demodulation of the new broadband digital receiver.关键词
