Securing the Skies: The Role of Radar Towers in Air Traffic Control
Quick Answer Radar towers are specialized steel structures—typically 15 to 50 meters tall —that support the surveillance radar systems used by air traffic controllers to monitor aircraft positions, altitudes, and speeds within terminal airspace. These towers provide the elevated, unobstructed vantage point required for radar antennas to achieve line-of-sight coverage over terrain and obstacles. Unlike the airport traffic control tower (ATCT), which is primarily for visual observation, the radar tower is an equipment-support structure designed to meet stringent structural standards (TIA-222-H/F/G), with hot-dip galvanized steel construction ensuring 30–50 years of corrosion protection in exposed airport environments. Radar systems mounted on these towers—such as the ASR-11 Digital Airport Surveillance Radar—provide primary surveillance coverage up to 60 nautical miles and secondary surveillance coverage up to 120 nautical miles , forming the backbone of modern air traffic management...
