Many wind-field mapping applications require range-resolved atmospheric velocity measurements at long range and/or with a temporal resolution sufficient to investigate turbulence. We argue that this capability can be achieved only by coherent laser radar systems that transmit energetic (>1 mJ) pulses. We describe such a system and describe single-pulse measurement of the range-resolved line-of-sight velocities, and show that the instrument-limited reproducibility of the measurements is 0.4 ms(-1).
许多风场测绘应用需要在远距离进行距离分辨的大气速度测量，和/或具有足以研究湍流的时间分辨率。我们认为，只有通过发射高能（>1 mJ）脉冲的相干激光雷达系统才能实现这种能力。我们描述了这样一种系统，并描述了距离分辨视线速度的单脉冲测量，结果表明测量的仪器限制再现性为0.4 m·s⁻¹。
