Research on DRFM Technique in Electronic Jamming

Digital radio frequency memory technology is more effective in electronic warfare technology,and it could jam enemy radar correspondingly by different processing and modulation of the received hostile signal.As the radar signal instantaneous bandwidth increases,the importance of technology of channelized DRFM has become increasingly prominent.This paper describes the basic principle of DRFM and the method for DRFM channelization,verifies the feasibility of DRFM by Matlab simulation,and analyzes the influence of the number of channels on the quality of synthesized signals,which provides a theoretical basis for DRFM in later project to realize the storage of higher instantaneous bandwidth.
