空气湍流已成为重大伤害和飞机损坏的主要原因。飞机前方的湍流的及时提前警告可以允许飞行员采取适当的行动以最小化潜在的损害，例如降低速度并保护乘客和不安全的物体，或者完全避免湍流。我们研究的目的是开发一种实用的机载激光雷达主动传感器，该传感器将在巡航高度的5 n英里（9.3公里）范围内检测晴空中的空气湍流。2007年2月，我们成功地测量了大约3 n英里的风速（5.6公里），并在同年7月的后续实验中，成功地在遇到空气湍流之前探测到它。2007财政年度开发了升级的5-n英里低空激光雷达，并且在地面测试中成功地测量了高达5 N英里范围内的风速。本文介绍了我们的激光雷达湍流传感器的总体发展计划和基本的飞行和地面实验的结果。
Air turbulence has become a major cause of significant injuries and aircraft damages. Timely advanced warning of turbulence ahead of an aircraft may allow pilots to take appropriate action to minimize potential damage, such as reducing speed and securing passengers and unsecured objects, or to avoid the turbulence altogether. The aim of our research is to develop a practical, onboard, Lidar-based proactive sensor that will detect air turbulence in clear air at a range of 5 n miles (9.3 km) at cruising altitudes. In February 2007 we successfully measured wind speeds approximately 3 n miles (5.6 km) ahead of an aircraft in low-altitude flight experiments, and in a subsequent experiment in July of the same year, we succeeded in detecting air turbulence before encountering it. An upgraded 5-n-mile Lidar for low altitudes was developed in fiscal year 2007, and has successfully measured wind speeds at ranges up to 5 n miles in ground tests. This paper describes the master development plan of our Lidar turbulence sensor and the results of basic flight and ground experiments.
