TOKYO, April 4, 2019 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has been awarded a contract by the "Romanian Air Traffic Services Administration (ROMATSA)", the national air traffic and aviation meteorology service provider in Romania, to supply a terminal Doppler lidar system (DIABREZZATM A Series) for use at Henri Coandă International Airport in Bucharest, Romania's busiest international airport. The system will be delivered in 2020 by Mitsubishi Electric under an order received from systems integrator "Centrul Pentru Servicii De Radiocomunicatii SRL (CSR)". Mitsubishi Electric was previously awarded a terminal Doppler lidar contract for Nice Côte d'Azur Airport, making the Henri Coandă supply contract the company's second in Europe and 10th worldwide. The company is expanding its weather radar and lidar business in global markets, aiming at net sales of about 2.5 billion yen by the fiscal year ending in March 2021.

DIABREZZA A Series Terminal Doppler Lidar

Terminal Doppler weather radar systems measure precipitation movements using microwaves to effectively detect wind shear around airports in wet-weather conditions. For maximum safety, however, detection is required under all conditions, not just during precipitation, which is why the integration of radar and lidar is crucial. This is true not only at large airports but also at midsize airports handling jet aircraft and where severe wind conditions occur.

A terminal Doppler lidar transmits laser beams and then detects light backscattered by dust or other particles in the air, enabling the system to use the Doppler frequency shift in the backscattered light to make line-of-sight measurements of wind speed and direction. Using this data, hazardous phenomena such as wind shear and microbursts can be detected within observable ranges. Mitsubishi Electric has extended this observation range to more than 20km with its planar waveguide amplifier, which complies with the standards and recommended practices of the International Civil Aviation Organization (ICAO), a United Nations' body that works to standardize global civil aviation operations and regulations.

Mitsubishi Electric has been delivering terminal Doppler lidar systems to airports since 2015. Six systems have been supplied and three more are scheduled to be delivered to international airports in Beijing Daxing (China), Nice Côte d'Azur (France) and Kansai (Japan), in addition to Henri Coandă. ROMATSA selected Mitsubishi Electric's terminal Doppler lidar system based on its high evaluation of the company's technology as well as its strong record of deliveries to major airports worldwide.
