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 whch 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 camed 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.

大气风的直接多普勒探测激光雷达系统

一种利用多普勒激光雷达测量风速的新方法正在开发中，有望提高我们的测量能力。这种风力激光雷达的演示将利用宾夕法尼亚州立大学激光大气测量项目(LAMP)最近开发的设备。激光大气风传感器的发展，以分析低层和中层大气风，将扩展LAMP仪器的能力。本文讨论了两个独特的概念，这导致了我们用多普勒激光雷达测量风的能力的进步。其中一个发展是四腔法布里-珀罗标准龙设计，这将允许标准龙在主动调谐控制下同时监测风。几项测量活动将展示风传感器系统，包括与met火箭、被动技术和雷达的比较。第二个发展是利用种子激光连续稳定法布里-珀罗标准子。预测系统性能将被呈现。
