3. Radar chart - Wikipedia

   en.wikipedia.org/wiki/Radar_chart

   A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative, but various heuristics, such as algorithms that plot data as the maximal ...

4. 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 ...

5. Plot (radar) - Wikipedia

   en.wikipedia.org/wiki/Plot_(radar)

   General operations plot: Used for tracking shipping on a large-scale chart. Was also used to display exercise boundaries, airplanes and other significant features of maritime interest. In the Royal Australian Navy, the scale used was generally 5 or 10 miles (8.0 or 16.1 km) per 1 inch (25 mm).

6. Atmospheric duct - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_duct

   In over-the-horizon radar, ducting causes part of the radiated and target-reflection energy of a radar system to be guided over distances far greater than the normal radar range. It also causes long-distance propagation of radio signals in bands that would normally be limited to line of sight.

7. Surface weather analysis - Wikipedia

   en.wikipedia.org/wiki/Surface_weather_analysis

   A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

   English: Radar plot depicting the data presented in Nutt, David, Leslie A King, William Saulsbury, Colin Blakemore. "Development of a rational scale to assess the harm of drugs of potential misuse" The Lancet 2007; 369:1047-1053. PMID:17382831.

9. Radar horizon - Wikipedia

   en.wikipedia.org/wiki/Radar_horizon

   And for the same examples : the radar horizon for the radar at a 1-mile (1.6 km) altitude will be 102-mile (164 km) and the one at 75 feet (23 m) will be 12-mile (19 km). Furthermore, layers with an inverse trend of temperature or humidity cause atmospheric ducting , which bends the beam downward or even traps radio waves so that they do not ...
