Farnborough, England, 20 July 2006: Lockheed Martin has announced that the Hong Kong Observatory has purchased a second WindTracer Doppler Lidar system which will be used at the Hong Kong International Airport.

Developed and produced by Lockheed Martin Coherent Technologies, WindTracer provides air traffic control personnel with advanced warning of wind hazards such as wind shear, microbursts, gust fronts, turbulence and crosswinds which enables them to offer precise, timely direction to pilots during takeoff and landing.

The Lidar system uses an eye-safe laser with precision pointing and scanning capabilities to reflect off aerosols 100 times smaller than the width of a human hair, collecting wind data over a broad volumetric area. The first WindTracer at Hong Kong International Airport was installed in 2002.

Using the WindTracer, the Hong Kong Observatory has developed the world’s first Lidar Windshear Alerting System (LIWAS). This system has been operating at the Hong Kong International Airport since end of 2005, continuously scanning approach and departure corridors, providing minute-to-minute warnings to aircraft landing and taking off at the airport.
