| 摘 要： | 采用半解析蒙特卡洛方法,开发了一套星载海洋激光雷达回波信号的仿真系统。通过输入激光雷达系统参数和仿真的环境参数,该系统能够模拟具有不同光学特性的大气和海洋的激光雷达回波信号。同时该仿真系统设计了用户友好的软件界面方便用户对输入参数进行操作,并直观地看到输出结果。利用该系统进行了多种仿真,例如不同类型水体以及不同散射相函数的情况,并将仿真结果与理论的激光雷达信号做了对比,具有较高的一致性。该系统对星载海洋激光雷达探测机理的研究有一定的指导意义。

| Abstract: | In this paper, a spaceborne oceanic lidar simulation system used semianalytic Monte Carlo method was developed. The system can simulate the lidar returns of the atmosphere and the ocean with different optical properties through entering the parameters of the lidar system and the environmental parameters. At the same time, a user-friendly software interface for users was designed to operate input parameters and observe the output results intuitively. A variety of simulations was done, such as different types of water and different scattering phase functions. The simulation results were highly consistent with the theoretical lidar equations. The system was important to the research on the detection mechanism of spaceborne oceanic lidars. |
