ABSTRACT:
The present invention is a lidar for detecting characteristics of the atmosphere, and in particular for detecting the speed and direction of objects such as air-borne particles and molecules in the atmosphere in order to determine the speed and direction of wind which is carrying them. The lidar comprises at least one lasing transmitter which transmits at least one lasing beam of radiation in the frequency range of ultraviolet light and which is swept along a path in the atmosphere so as to strike objects in the atmosphere causing backscatter radiation which is received by a receiver for determination of the Doppler shift of the objects being struck. The lidar is moved in a vehicle such as a satellite, so that wind speeds and directions at a number of altitudes and over a large area can be measured.
