Danish radar manufacturer Terma has secured a contract to supply the newly developed anti-icing antenna to Sofia Airport, Bulgaria.
Under the terms of the contract, the company will deliver anti-icing antennas as part of an upgrade of the SCANTER surface movement radar (SMR) system supplied earlier.
The new anti-icing antenna is expected to help prevent problems associated ice building on antennas spinning with 60 rotations per minute (RPM) used for airport surveillance.
The ice on the antenna not only reduces the life of the equipment but also poses a security risk if the ice ejects off the antenna with the risk of landing in public areas.
The company claims the anti-icing antenna can prevent ice from building up from +5º Celsius.
The SMR systems enable air traffic controllers to detect and guide aircraft and vehicles such as baggage carriers, buses, supply trucks and staff cars.
The radar has the ability to control the transmitted power in sectors for increased robustness against interference between radar stations, and to minimise multi-path reflections, according to Terma.
Air traffic controllers use SMR systems to detect and guide aircraft and vehicles on the ground surface of the airport to ensure safety.
Terma’s SMR systems are currently operation at China’s Chengdu Shuangliu International Airport and Romania’s Bucharest Otopeni International Airport.
