A primary radar or primary surveillance radar (PSR) is a conventional radar sensor that illuminates a large portion of space with an electromagnetic wave and detects the waves that reflect from targets within that space. The term thus refers to a radar system used to detect and localize potentially non-cooperative targets.
Insect radar. Surveillance radar (mostly X and S band, i.e. primary ATC Radars) Tracking radar (mostly X band, i.e. Fire Control Systems) Wearable radar and miniature radar systems are used as electric seeing aids for the visually impaired, as well as early warning collision detection and situational awareness

Perimeter surveillance radar (PSR) is a class of radar sensors that monitor activity surrounding or on critical infrastructure areas such as airports, [1] seaports, military installations, national borders, refineries and other critical industry and the like. Such radars are characterized by their ability to detect movement at ground level of ...
The sophisticated systems at large airports consist of two different radar systems, the primary and secondary surveillance radar. [1] The primary radar typically consists of a large rotating parabolic antenna dish that sweeps a vertical fan-shaped beam of microwaves around the airspace surrounding the airport. It detects the position and range ...
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
The name of the airport was reported to be a suggestion from the people of Karo to the government and later granted by the Ministry of Transportation. [6] The name consists of two words: 'Kuala,' a Malay and Indonesian word for 'river mouth;' [7] and 'Namu' or 'Namo,' the Karonese for 'deep sea.' [8] Thus, 'Kualanamu' means 'meeting point.' [6] Kualanamu is one of the very few airports in the ...
A Joint Surveillance Target Attack Radar System (JSTARS) ISTAR stands for intelligence, surveillance, target acquisition, and reconnaissance. In its macroscopic sense, ISTAR is a practice that links several battlefield functions together to assist a combat force in employing its sensors and managing the information they gather.
