phase tracking
[/feɪz ˈtrækɪŋ/]
noun
rastreamento de fase
1. The process of monitoring and maintaining synchronization of the phase of a signal or oscillation relative to a reference signal or standard
Phase tracking is essential in GPS receivers to maintain accurate positioning signals.
O rastreamento de fase é essencial em receptores GPS para manter sinais de posicionamento precisos.
2. In telecommunications and signal processing, a technique used to keep the phase of a received signal locked to the phase of a reference oscillator
The phase-locked loop uses phase tracking to synchronize the local oscillator with the incoming signal.
O circuito de malha travada por fase usa rastreamento de fase para sincronizar o oscilador local com o sinal recebido.
3. In control systems, the continuous adjustment of a system's response to maintain phase alignment with a desired reference
Effective phase tracking prevents signal drift and improves system stability.
O rastreamento de fase eficaz evita a deriva do sinal e melhora a estabilidade do sistema.
Phase tracking is a highly specialized technical term predominantly used in telecommunications, electrical engineering, aerospace, and signal processing industries. It is widely used in both Brazil and the USA in academic and professional contexts, particularly in discussions of GPS technology, radar systems, and radio communications. The term remains consistent across both countries with minimal regional variation.
