Frequency agility is the ability of a radar system to quickly shift its operating frequency to account for atmospheric effects, jamming, mutual interference with friendly sources, or to make it more difficult to locate the radar broadcaster through radio direction finding. The term can also be applied to other fields, including lasers or traditional radio transceivers using frequency-division multiplexing, but it remains most closely associated with the radar field and these other roles generally use the more generic term "frequency hopping".

dbo:abstract
  • Agilitat freqüencial, en telecomunicacions, és la capacitat d'un sistema de telecomunicacions via ràdio-freqüència (per exemple radars) de canviar la freqüència d'operació amb l'única finalitat d'evitar efectes adversos com poden ser problemes atmosfèrics, interferències radioelèctriques voluntàries o involuntàries. L'agilitat freqüencial s'aplica al transceptor de ràdio per exemple emprant el sistema de multiplexació per divisió de freqüència. Cal diferenciar entre agilitat freqüencial i el salt de freqüència (frequency hopping): els sistemes de salt estan contínuament canviant de freqüència, són per exemple el sistema Bluetooth. En canvi, els sistemes d'agilitat, només canvien de freqüència en cas de necessitat, per exemple els sistemes radar i ZigBee. (ca)
