Abstract

A new digital radio frequency memory (DRFM) system architecture based on digital channelized receiver is introduced. The theory of channelized receiver is stated and the realization structure based on polyphase filters is derived, and the diagram of radar countermeasure system based on this idea is proposed. The DRFM system based on digital channelized receiver take the advantage of broadband coverage of channelized receiver, and guarantees the frequency accuracy of the reproductive signals. The system can significantly reduce the requirement for calculation resources, the complex modulation process can easliy be achieved due to the decimated low speed data rate.
