Radar display

A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation, a small portion of which backscatter off targets and return to the radar system. The receiver converts all received electromagnetic radiation into a continuous electronic analog signal of varying voltage that can be converted then to a screen display.

Radar

Radar is a system that uses radio waves to determine the distance (ranging), direction, and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term radar has since entered English and other languages as an anacronym, a common noun, losing all capitalization.

Green

Green is the color between cyan and yellow on the visible spectrum. It has 295–350 different shades. It is evoked by light which has a dominant wavelength of roughly 495–570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.

radar

Noun

1. In full primary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing radio waves (usually microwaves) which are sent towards the object and which reflect off its surfaces; also, the field of study of this method.
2. In full secondary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing signals transmitted by the object in response to radio waves sent towards the object.

Verb

1. To use a radar apparatus (noun senses 1, 1.1, or 2) on (someone or something); to scan (someone or something) with, or as if with, radar.

blip

Noun

1. A small dot registered on electronic equipment, such as a radar or oscilloscope screen.
2. A short sound of a single pitch, usually electronically generated.

Verb

1. To make a short beep sound.
2. To change state abruptly, such as between off and on or dark and light, sometimes implying motion.

green

Noun

1. The color of grass and leaves; a primary additive color midway between yellow and blue which is evoked by light between roughly 495–570 nm.
