我们提出了模拟能力和实验数据的多普勒激光雷达的平流层和较低的中间层，使用边缘的分子碘过滤器在差分测量，以提供频率歧视。模拟结果表明，在30分钟内的1.5公里分辨率的高度为55公里的风测量能力。实验上，从18至45公里的风矢量分量测量每20分钟。分子蒸汽过滤器提供了很大的优势，系统的稳定性，操作在低于最佳的天气条件下，和简单的数据分析。
We present both modeled capabilities of and experimental data from a Doppler lidar for the stratosphere and the lower mesosphere that uses the edge of a molecular iodine filter in a differential measurement to provide frequency discrimination. Modeled results show a capability for wind measurements to an altitude of 55 km with 1.5-km resolution in 30 min. Experimentally, wind-vector components from 18 to 45 km are measured every 20 min. The molecular-vapor filter provides great advantages with regard to system stability, operation in less-than-optimum weather conditions, and simplicity of data analysis.
