摘要

摘要本文涉及用于探测大气云层的广角激光雷达时空信号的蒙特卡罗建模。通过计算实验，我们研究了单静态和双静态传感方案下激光雷达信号的特征，这使得分析云环境的光学和微物理特性成为可能。在探测薄云层时，激光雷达信号看起来像一个膨胀和衰减的光环。研究表明，在双静态方案中，激光雷达信号的特征是在主光环内短时间出现第二个光环。

Monte Carlo Simulation of Wide-Angle Lidar Signals

Abstract

The paper deals with Monte Carlo modeling of spatiotemporal signals of wide-angle lidars for probing atmospheric clouds. Using computational experiments, we study the features of lidar signals for monostatic and bistatic sensing schemes which make it possible to analyze the optical and microphysical properties of the cloud environment. When probing thin cloud layers, the lidar signal looks like an expanding and attenuating light ring. It is shown that for a bistatic scheme a second ring, which appears for a short time inside the main one, is characteristic of the lidar signal.
