Doppler Lidar Systems

Products – Large-scale Coherent Doppler Lidar System

Pulse laser safe to the human eye measures wind direction and speed in real time

Main Features

  • Applying the WGA technology, it measures wind speed in the boundary layer atmosphere up to a distance of 30km* horizontally.
  • Unlike radar that measures precipitation, the wind speed can be measured when there is no precipitation.
  • This system uses laser with an eye-safe wavelength of 1.5 µm.
  • Monitoring management software offers fully automatic measurement and automatic scheduling of measurement.
  • Remote operation and monitoring possible using LAN or high-speed network.
  • Built-in shelter enables system to be relocated safely if necessary

(* Actual observation range varies according to the aerosol condition of the atmosphere.)


  • Meteorological observations (three-dimensional profile of atmospheric wind, turbulence)
  • Air traffic safety (measures low-level wind shear around airports, sudden gusts, and aircraft wake turbulence)
  • Air environment consultation (urban heating, monitoring of substances released in emissions from factories, application in wind power generation)
