Digital radio frequency memory (DRFM) technology can keep jamming signals being coherent with radar signals,and it has become an important method to jam new system Radar.In this paper,the fundamental principle of DRFM and the implementation of channelized DRFM are introduced.In addition,the impact of the number of channels,the overlap bandwidth of channels and the synthesis method of signals on the quality of signal synthesis is analyzed in detail by simulation.It also provides a theoretical basis for the broadband DRFM system.

Key words: DRFM;digital channelization;signal synthesis
