What Is The Difference Between Lidar For Ranging And Doppler Lidar For Measuring Wind Speed

The principle of the two is different, ranging is the use of a simple speed of light time product divided by two, wind measurement is the use of aerosols or air molecules to generate motion and Doppler frequency shift, from the light source, the back of the receiving spectroscopic system, etc. are different, the latter wind measurement is more complex, the requirements are more precise.
