Aims: This paper aims to improve the instantaneous bandwidth, computing capability and flexibility of the digital radio frequency memory(DRFM) jammer. Methods: The DRFM principle and channelized receiving technology were combined to propose a design scheme of the signal processing module for high-performance broadband DRFM jammers. Meanwhile, advanced signal processing devices, high-performance ADCs and DACs were used to design a hardware platforms, with the corresponding software designed. Results: The experiment results showed that the instantaneous bandwidth of the hardware platform could reach 4 GHz, that the signal storage depth could reach round 200 ms, and that the minimum processing delay could reach round 600 ns. Conclusions: This prototype can achieve effective jamming to the new radar systems.
