phase wrapping problem
[/feɪz ˈræpɪŋ ˈprɒbləm/]
nounpl: phase wrapping problems
problema de envolvimento de fase
1. A technical issue in signal processing and interferometry where phase measurements become ambiguous due to the periodic nature of the phase function, causing discontinuities when phase values wrap around from 2π to 0
The radar system encountered a phase wrapping problem when measuring distances beyond one wavelength.
O sistema de radar encontrou um problema de envolvimento de fase ao medir distâncias além de um comprimento de onda.
2. In synthetic aperture radar (SAR) and interferometric applications, the inability to distinguish between phase values that differ by multiples of 2π radians
Phase unwrapping algorithms are essential to solve the phase wrapping problem in interferometric data.
Algoritmos de desenvovimento de fase são essenciais para resolver o problema de envolvimento de fase em dados interferométricos.
This is specialized technical terminology primarily used in engineering, physics, and signal processing fields. It is more prevalent in academic and industrial research contexts in both Brazil and the United States, particularly within radar technology, geophysics, and optical measurement communities. The term is largely discipline-specific and rarely encountered in everyday Portuguese or English usage.
