This guide is organized using the color bars that highlight the titles and headings. The yellow color refers to headings for major topics. The green color highlights subtopic headings within the major topics. Light red color indicates subtopics within other subtopics.
Radar reflectivity (return levels) is calibrated as rainfall rates, inches per hour. The manufacturer will design the system with three or four levels of returns. These will be divided equally between the minimum and maximum. typical three-color system will be green, yellow and red, with red being the most severe.

A typical on-board weather radar system for a high performance aircraft uses a nose-mounted antenna that gimbals. It is usually controlled by the inertial reference system (IRS) to automatically adjust for attitude changes during maneuvers so that the …
What do the Radar Colors Mean? – RadarNow!
2018年1月16日 · The colors are the different radial velocities measured by the radar. In velocity images, red colors indicated wind moving away from the radar with green colors indicating motion toward the radar. The transition zone between incoming and outgoing winds are indicated the gray-ish colors between the two.
Weather Radar Fundamentals
Base radial velocity images provide information about wind speed and direction. These are determined by whether a target is moving toward or away from the radar along a radial direction. In this example, warm colors (reds) indicate motions away from the radar and cool colors (greens) represent motion toward the radar.
About our WSR 88-D Radar - National Weather Service
The WSR-88D obtains weather information (precipitation and wind) based upon returned energy generated and received at the Radar Data Aquisition (RDA) unit (see animated diagram below). The radar emits a burst of energy (green), from a 28 foot diameter antenna inside the radome (the white, soccer ball covering).

Radar systems are available with either a 10 inch or 12 inch antenna array (dish or plate). A 10 inch antenna will fit the under-wing radar pod on a single, or in the nose of a light twin. Cabin-class twins (and larger) can generally accommodate a 12 inch antenna.
