Surveillance radar detects, tracks and monitors objects in its coverage area by transmitting radio waves and analyzing the returned signals. It provides real-time information on the position and movement of targets, such as aircraft, ships or vehicles. Surveillance radar is used in various applications including air traffic control, maritime navigation and military operations to ensure safety, security and efficient traffic management.
Surveillance radar is to improve situational awareness by providing continuous and precise tracking of objects in a specified area.
This information is essential for coordinating and controlling traffic, preventing collisions and ensuring safe navigation. In air traffic control, for example, surveillance radar helps manage the movement of aircraft, ensuring they maintain safe distances from each other and obstacles. In the maritime environment, it assists in the navigation and surveillance of vessels, improving the safety and efficiency of busy waterways.
Primary Surveillance Radar (PSR) provides information on the position, distance and port of objects within its coverage area.
It determines the range of an object by measuring the time it takes for the transmitted radar signal to return after bouncing off the target. Azimuth, or direction, is calculated based on the angle at which the reflected signal is received. The PSR does not depend on any equipment on target, making it useful for detecting and tracking objects that may not have transponders or other cooperative systems
