Doppler Lidar / Radar Systems


Measurement Principle

The system transmits a laser beam into the air, receives the light backscattered by aerosols*, and analyzes the atmospheric properties using the received signal. The signals from moving objects have a Doppler shift proportional to their speed, which enables the velocity of the aerosols to be calculated. As a result, the direction and speed of the wind can be measured.

Since a Doppler Lidar transmits pulses of light repetitively while scanning the backscattered light from aerosols, the range and direction of particles can be measured simultaneously.

*Tiny dust particles with diameters of 1/10 to several microns in the atmosphere.
