Disambiguation

Refers to a signal-processing algorithm used in tracking and estimation systems; may appear in UAP radar analysis or target tracking contexts. Not to be confused with cognitive psychology literature on 'fading memory' as a general phenomenon.

Concept

scientific-term

A recursive signal-processing algorithm that weights recent measurements exponentially more than older ones, used in tracking, navigation, and radar systems.

Um algoritmo de processamento de sinais recursivo que pondera exponencialmente as medições recentes mais do que as antigas, utilizado em rastreamento, navegação e sistemas de radar.
