Dual-frequency Doppler-lidar method of wind measurement
Abstract:
In this new method [dual-frequency Doppler-lidar (DFDL)] of remote wind sensing, two optical beams of unlike frequency are superimposed in the sensed volume. The velocity information is obtained from the difference in the Doppler shifts of light scattered from the two beams by aerosols moving with the air. The DFDL signal spectrum and expressions for SNR are derived. Attractive characteristics of DFDL include resilience to optical imperfections of the turbulent atmosphere and a potential for simultaneous measurement of the three components of wind velocity.
