Coherence time

  "id": "MLC-T-MET-004485",
  "term": "Coherence time",
  "field": "Meteorology and atmospheric science",
  "definition": "The duration over which a wave maintains a predictable phase relationship, or the time interval during which a signal's phase can be considered constant. In radar meteorology, it indicates how long a radar pulse remains coherent enough for effective signal processing, such as Doppler velocity estimation. This parameter is inversely related to the spectral width of the received signal.",
