Information on Digital Radio Frequency Memory

Digital radio frequency memory (DRFM) is an approach being adopted by modern electronic attack (EA) systems to combat pulse-compression radar. A digital radio frequency memory system receives radar pulses, stores these in a digital delay line, and retransmits then some time later. This causes the radar to receive a return that places the target in an incorrect location.
     Pulse compression and pulse coding radars must vary their compression or coding parameters to minimise the effects of digital radio frequency memory jamming.
