anti-jamming
Blocks electronic interference
Anti-jamming describes technology or techniques designed to resist electronic interference with communications or signals.
Military and navigation systems use anti-jamming measures to ensure signals remain reliable even when an adversary attempts to disrupt them: anti-jamming GPS receivers, anti-jamming radar systems.
The term appears most often in defense and aerospace contexts.
