Coherent target

{
  "id": "MLC-T-MET-004490",
  "term": "Coherent target",
  "field": "Meteorology and atmospheric science",
  "definition": "A radar target whose returns keep a definite phase relation to the transmitted wave from one pulse to the next, as with a rigid point scatterer such as an aircraft or fixed ground clutter. Its motion appears as a steady pulse-to-pulse phase change, from which Doppler velocity follows. Distributed targets such as rain differ, because their echo amplitude fluctuates as the many scatterers shift relative to one another.",
