Azimuth-Range Indicator

An Azimuth-Range Indicator (ARI) is a device used in radar systems to display the azimuth (horizontal angle) and range (distance) of a target. It provides real-time information about the location of a target relative to the radar system.

The ARI typically consists of a circular display with a rotating cursor or marker that represents the azimuth angle. The range is usually displayed as a radial scale along the edge of the display. The cursor moves around the display as the radar antenna scans the surrounding area, indicating the direction and distance of detected targets.

The ARI is an essential tool for radar operators as it allows them to quickly and accurately determine the position of targets. It is commonly used in military applications, air traffic control systems, and weather radar systems.

In addition to displaying azimuth and range, some ARIs may also provide additional information such as target speed, altitude, and identification. These advanced indicators are often used in more sophisticated radar systems for tracking and surveillance purposes.

Overall, the Azimuth-Range Indicator plays a crucial role in radar operations by providing operators with real-time information about the location and characteristics of detected targets.
