  2. Weather radar - Wikipedia

    en.wikipedia.org/wiki/Weather_radar

    Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

  3. Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Doppler_radar

    These detect motion from vehicles and personnel for night and all weather combat operation. Modern police radar guns are a smaller, more portable version of these systems. [8] [9] Early Doppler radar sets relied on large analog filters to achieve acceptable performance.

  4. List of radar types - Wikipedia

    en.wikipedia.org/wiki/List_of_radar_types

    The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...

    en.wikipedia.org/wiki/Advanced_Technology...

    By and large, meteorological monitoring is done operationally by relatively legacy weather radar systems – in the United States, the NEXRAD network has been the primary weather radar network since the early 1990s. For the first 20 years of operations, its data output was, in comparison to modern schemes, considerably more modest.

  6. Canadian weather radar network - Wikipedia

    en.wikipedia.org/wiki/Canadian_weather_radar_network

    The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation , its motion and the threat it poses to life and property.

  7. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites are mainly of two types: polar orbiting (covering the entire Earth asynchronously) or geostationary (hovering over the same spot on the equator ).

  8. Plan position indicator - Wikipedia

    en.wikipedia.org/wiki/Plan_position_indicator

    A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...

  9. Radar - Wikipedia

    en.wikipedia.org/wiki/Radar

    Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
