Mitsubishi Electric Corporation reported that Météo-France, the national meteorological service in France, awarded it a contract to supply a Terminal Doppler Lidar system (DIABREZZA™ A Series) for use at Nice Côte d’Azur Airport. Nice Côte d’Azur Airport, France’s second-busiest international airport, handled 13.3 million passengers in 2017. The 1.5 micrometer (eye safe) solid state laser emits light. Then the lidar system measures the light scattering from dust and other particles in the air and measures the time it takes for the light to bounce back to calculate the wind speed of in an area of more than 20km away.
Terminal Doppler Lidar at Nice Côte d’Azur Airport to be First in Europe
Mitsubishi Electric says that this order for the Nice Côte d’Azur Airport will provide its first Terminal Doppler Lidar to be used in Europe. The company intends to boost its lidar and weather radar business, including Terminal Doppler Lidar, in international markets to net sales of about 2.5 billion yen per year by March 2021.
The company notes that neither radar using microwaves to measure precipitation nor Terminal Doppler Weather Radar systems for detecting wind shear around airports are effective in clear weather.
Wind shear detection is required under all conditions to maximize prevention of aircraft accidents not just during precipitation. Mitsubishi Electronic says that this demand for wind shear detection under all conditions makes the integration of Doppler Lidar with radar especially crucial for large-scale airports.
The company developed a planar waveguide amplifier that uniquely extends the line-of-sight wind speed observation range to more than 20km. The waveguide amplifier complies with Standards and Recommended Practices of the International Civil Aviation Organization (ICAO), an organization ensuring that civil aviation operations and regulations adhere to international standards.
The company provided Terminal Doppler Lidar systems to airports since 2015. So far, five systems from the company are currently operating at international airports in Tokyo (Japan), Narita (Japan), and Hong Kong (China). The company has scheduled another two Terminal Doppler Lidar Systems to be delivered to Beijing Daxing (China) and Antalya (Turkey) international airports in 2018, prior to the delivery of the system to Nice Côte d’Azur Airport.
