本文描述了一个实验室原型无人值守激光雷达系统的发展，用于测量10公里的气溶胶剖面和3公里的臭氧剖面。在无人值守系统中需要考虑的一个因素是稳健的、人眼安全的光学设计，它可以提供必要的信号水平和动态范围，以产生所需高度、分辨率和精度的轮廓。一个同样重要的考虑是在一系列大气条件下计算气溶胶和臭氧剖面的一套算法。NEXLASER采用大气状态模型来帮助识别和适应它必须遇到的各种条件。演示了算法的信噪比要求，并与硬件设计相关。在模拟大气条件下验证了系统的性能。
This paper describes the development of a laboratory prototype unattended LIDAR system to measure aerosol profiles to 10km and ozone profiles to 3km. One consideration in an unattended system is a robust, eye-safe optical design that can provide the necessary signal levels and dynamic range to produce profiles at required height, resolution, and accuracy. An equally important consideration is a set of algorithms to compute aerosol and ozone profiles under a range of atmospheric conditions. NEXLASER employs an atmospheric state model to help identify and adapt to the varied conditions it must encounter. The signal-to-noise requirements of the algorithms are demonstrated and related back to hardware design. Performance of the system is demonstrated with simulated atmospheric conditions.
