摘要
针对机载双波长偏振激光雷达的技术特点,结合搭载遥感飞机的基本性能,分析了激光雷达的设计方法;仿真计算了激光雷达的配置参数;解决了激光雷达应用于航空平台的一些关键技术。通过实验取得了初步的结果,地基实验表明,激光雷达达到设计指标要求的探测能力。初步的飞行实验结果表明,激光雷达采用的关键技术符合航空平台关于体积、重量、功耗以及环境适应性的要求。利用激光雷达的主动探测能力,结合机上同时搭载的被动遥感仪器,将实现国家关注的大气成分及其环境要素的科学实验研究目标。
A two-wavelength polarization airborne lidar is designed for detecting three-dimensional distributions of aerosols and clouds and its interaction on both regional and global dimension.The design and operation of the lidar system are discussed.Simulation results of the lidar specifications are presented.Some key techniques adopted in developing the airborne lidar are depicted.The ground experimental result suggests that the lidar system can achieve the detection performance as wanted.Initial result from airborne measurement shows that the airborne lidar meets the aviation applications on weight,size,power and operating environment restrictions.In the future,integrated atmospheric observations using lidar along with other passive remote sensing instrument aboard on the aircraft,will improve our understanding of atmospheric composition and environment element.
