Abstract
A new approach to sensing the wind velocity using Doppler lidar is being developed which promises to improve our measurement capability. Demonstration of this wind lidar will utilize the recently developed equipment prepared under the Laser Atmospheric Measurements Program (LAMP) at Penn State University. Development of the laser atmospheric wind sensor to profile lower and middle atmosphere winds will extend the capabilities of the LAMP instrument. This paper discusses two unique concepts which lead to advances in our ability to measure winds with Doppler lidar. One development is the quad-cavity Fabry-Perot etalon design, which will allow the etalon to simultaneously monitor the wind while under active tuning control. Several measurement campaigns will be carried out to demonstrate the wind sensor system including comparisons with met rockets, passive techniques, and radar. The second development is the use of the seed laser to stabilize the Fabry-Perot etalon continuously. Predicted system performance will be presented.
