Manipulating the Threat
Military airborne, shipborne, and ground based radar systems are designed around their ability to function in a jammed environment. Modern radars, e.g. pulsed Doppler radars, have a fixed phase relationship between the transmitted and received RF signals because they are operating on a basis of coherent processing.
DRFM Jamming Technology
Digital Radio Frequency Memories (DRFM) have become the core of any electronic jamming system. The DRFM is a device with storage methods in which the radar signal itself is stored, modulated with jamming signals and then retransmitted to the threat.
