TOKYO, September 2, 2015Mitsubishi Electric Corporation announced today that it has been awarded a contract by Hong Kong Observatory (HKO), a department of the Hong Kong Government, to supply Hong Kong International Airport (HKIA) with two Terminal Doppler Lidar systems capable of detecting nearby low-level wind shear and turbulence during non-precipitation conditions. The system uses a single-frequency pulse laser to capture the movements of dust and tiny particulates in the air to take measurements.

Dimension 2.8W x 2.2D x 2.6H(m)
Weight Less than 2 ton

In Japan, Mitsubishi Electric supplied Tokyo International Airport with similar systems in March.

Previously, the company supplied HKIA with a Terminal Doppler Weather Radar (TDWR), which detects wind shear and turbulence during precipitation by using microwave signals to measure the movement of rain drops in the atmosphere. The combination of the TDWR and Terminal Doppler Lidar systems will give the airport the capability to observe wind shear and turbulence under all weather conditions, ensuring heightened safety.

Going forward, Mitsubishi Electric will continue to develop increasingly advanced and ever-more reliable Doppler Lidars as one of the world’s leading suppliers of these systems.
