RADAR SCREEN Meaning and
Definition
-
A radar screen is a visual representation of the data collected and processed by a radar system. It is an electronic display that presents real-time information about objects detected by the radar's emission of radio waves and their subsequent reflection from those objects. Typically, the radar screen is composed of a rectangular grid, with the horizontal and vertical axes representing range and azimuth (or bearing) respectively.
The radar screen provides a detailed view of the detected objects and their relative positions. It displays the bearing, range, and sometimes the altitude of the detected targets. The position of the radar antenna is usually depicted by a central point or symbol on the screen. The radar echoes, or blips, produced by reflected radio waves from targets, are shown as small dots or other graphical symbols on the radar screen, often referred to as radar returns.
The screen may include various additional features and indicators to enhance situational awareness, such as range rings to show the distance from the radar's location and azimuth lines to help determine the bearing of the targets. It may also provide tools for measuring distances and angles, tracking moving targets, and displaying historical radar information.
Radar screens are widely used in aviation, maritime navigation, military operations, weather monitoring, and air traffic control. They play a vital role in providing real-time information to operators, enabling them to track and monitor the movements of objects within the radar system's coverage area accurately.

Etymology of RADAR SCREEN
The word "radar screen" combines two distinct components: "radar" and "screen".
The term "radar" itself is an acronym for "Radio Detection and Ranging". It was coined during World War II when scientists and engineers developed a system that used radio waves to detect and locate objects such as aircraft and ships. The term "radar" was adopted due to the nature of the technology that involved radio waves.
The term "screen" refers to a surface that displays information or images. In the context of radar, the display screen refers to the visual representation of the data collected by the radar system. The use of the screen allows operators to observe and interpret the information more easily.
Therefore, the etymology of the term "radar screen" is the combination of the acronym "radar" representing the technology, and "screen" representing the display surface where the radar information is presented.
