DRFM
A technology that digitally captures a radar pulse and re-transmits a modified copy, letting a jammer create realistic false targets or range and velocity deception. It is a foundational building block of modern coherent electronic attack.

Why it matters
DRFM is why modern deception jamming is convincing: by storing and replaying a radar’s own pulse it creates false targets a legacy radar cannot easily reject, so operators must assume some returns are fabricated.
