Abstract

Autodyne coherent lidars, i.e., the lidars with intracavity reception of the echo-signals proved to be of efficient for studying the atmosphere^1-3. They possess high sensitivity and high noise immunity. They make it possible to determine few parameters in question simultaneously, namely: the absorption along the path, the distance to the retroreflector and its velocity. The ways for determining the above parameters are described.
