In research of Electronic Countermeasure (ECM) recently, Jamming source based on Digital Radio Frequency Memory (DRFM) technology and digital channelization technology has attracted more attention. This paper schemes out a novel DRFM jamming system structure, which implementing the channelized receiving with Analysis Filter Bank (AFB) and the modulated signal reconstruction with Synthesis Filter Bank (SFB). Jamming information modulation is carried out in an optimized way with improved Signal Noise Ratio (SNR) of the generated signal. Simulation results have verified the validity of this scheme. Keywords: Digital Radio Frequency Memory (DRFM), Analysis Filter Bank (AFB), Synthesis Filter Bank (SFB), deceptive jamming.
