What is an air surveillance radar?
An air surveillance radar, also known as an air traffic control radar, is an essential part of air traffic management systems used to monitor and manage aircraft movements within a specific airspace. These radars work by transmitting radio waves into the surrounding airspace and detecting reflections or echoes from the aircraft within range.
The radar system then processes these echoes to determine the position, altitude, speed and heading of each aircraft. This information is essential for air traffic controllers to maintain safe separation between aircraft, sequence arrivals and departures, and provide guidance to pilots during the approach and departure phases.
Aerial surveillance radars typically operate using various radar technologies, such as primary surveillance radar (PSR) and secondary surveillance radar (SSR).
PSR relies on the reflection of radio waves from aircraft to detect their presence and determine their position and range. SSR complements PSR by using transponders on aircraft to receive and respond to radar interrogations, providing additional information such as aircraft identification and altitude derived from the Mode C or Mode S transponder.
The operation of air radar involves emitting radio waves from the radar antenna, which propagate through the airspace and interact with aircraft in the radar coverage area.
When these waves encounter an aircraft, some of the energy is reflected back into the radar receiver. The radar system analyzes the timing and characteristics of these reflections to calculate the aircraft’s position, speed and other relevant parameters.
This data is constantly updated and displayed to air traffic controllers, allowing them to monitor and manage air traffic efficiently and safely.
Airport Surveillance Radar (ASR) offers several advantages for air traffic management at airports:
Precise Aircraft Tracking: ASR provides precise, real-time tracking of aircraft in terminal airspace, allowing controllers to monitor arrivals, departures and ground movements with high precision.
Increased Safety: By providing continuous monitoring and awareness of aircraft positions and movements, ASR helps maintain safe separation between aircraft, reducing the risk of mid-air collisions and ground incidents.

Improved efficiency: ASR allows controllers to efficiently manage traffic flow, optimize runway utilization and sequence aircraft for approach and departure, thereby improving airport capacity and operational efficiency.
How does air radar work?
All-Weather Capability: Modern ASR systems are designed to operate effectively in various weather conditions, including low visibility scenarios, ensuring continuous monitoring and safe operations even in adverse weather.
Air Traffic Management Integration: ASR integrates seamlessly with other air traffic management systems and technologies, such as radar data processing systems, automation tools and communications networks, supporting the coordinated and efficient management of airspace.
Overall, ASR plays a crucial role in ensuring the safe, orderly and efficient movement of aircraft through airport terminal areas, contributing to the overall safety and performance of the aviation system.
