Atmospheric LIDAR Engineering

Course Description

Light detection and ranging (LIDAR) is used for several applications and is analyzed for subsystems (transmitter, receiver, and data acquisition). This course will help you understand how LIDAR techniques are used to characterize various atmospheric constituents and parameters. By the end of this course, you will have mastered the tradeoffs among different types of LIDAR for specific applications.
