  "term": "I and Q channels",
  "field": "Meteorology and atmospheric science",
  "definition": "The in-phase (I) and quadrature (Q) components of a complex signal, used in radar and telecommunications to represent the amplitude and phase information of a modulated waveform. In Doppler weather radar, these channels are processed to extract information about the velocity and intensity of precipitation. The I and Q signals are typically 90 degrees out of phase with each other.",
