Abstract:  The measurement of atmospheric wind field has great practical application value in the fields 
 of environment, aviation, aerospace and so on. At present, there are few reports about the 
short-range atmospheric wind field. Moreover, traditional pulse laser wind measurement system 
often has a low-altitude blind area, which can not satisfy the requirements of the measurement 
of short-range low-altitude wind field. A short-range wind measurement system was designed and set up 
to achieve close-range wind field information measurement based on a continuous laser light source. 
The error of the experimental measurement results compared with thate of the anemometer at the same time
is are less than 3\%. The developed continuous laser wind measurement 
system is assembled with appropriate scanning mode, which can serve for the actual measurement of short-range wind field.

Key words: coherent wind measurement, continuous laser, Doppler effect, short-range wind field
