phase ambiguity

[/feɪz æmˈbɪɡjuəti/]
nounpl: phase ambiguities
ambiguidade de fase
1. A condition in signal processing and telecommunications where multiple phase values produce identical or indistinguishable signal measurements, making it impossible to determine the true phase without additional information
The GPS receiver encountered phase ambiguity when trying to determine the exact wavelength of the carrier signal.
O receptor GPS encontrou ambiguidade de fase ao tentar determinar o comprimento de onda exato do sinal portadora.
2. In radar and sonar systems, the uncertainty that arises when the phase difference between transmitted and received signals cannot uniquely identify the target's distance or velocity
Phase ambiguity in synthetic aperture radar requires careful calibration to resolve multiple possible solutions.
A ambiguidade de fase no radar de abertura sintética requer calibração cuidadosa para resolver múltiplas soluções possíveis.
3. A mathematical or computational problem where phase information is lost or becomes cyclical, preventing unique reconstruction of the original signal
Researchers developed algorithms to overcome phase ambiguity in holographic imaging applications.
Pesquisadores desenvolveram algoritmos para superar a ambiguidade de fase em aplicações de imageamento holográfico.
Phase ambiguity is primarily a technical term used in engineering, telecommunications, GPS technology, and signal processing fields. It is more prevalent in academic and professional contexts in both Brazil and the USA rather than in casual conversation. The term is identical in Portuguese and English technical literature, reflecting the international nature of scientific terminology.
