The oceanic lidar, which has the advantage of profiling the properties of the upper ocean, is a promising active remote sensing tool for complementing the passive ocean color remote sensing in the three-dimensional observation of ocean. This paper introduces the design and validation of a shipborne multiple-field-of-view (MFOV) lidar. With the input of simultaneous in situ data, the lidar signals and the retrieved lidar attenuation coefficient α are validated quantitatively using simulation results. The simulation methods include quasi-single-scattering lidar equation, Monte Carlo (MC) method, and analytical model. The experimental lidar signals are consistent with the simulated lidar signals with coefficient of determination R²>0.91, and α retrieved from experimental lidar signals corresponds well with the simulated values with root mean square (RMS) of relative error δ<0.18. The results at different field of view (FOV) indicate the relationship between the beam attenuation coefficient c, diffuse attenuation coefficient K_d, and α. This work is beneficial to the research on the mechanism, retrieval and application of oceanic lidar.

具有描述上层海洋特性的优势的海洋激光雷达是一种有前途的主动遥感工具，可用于在海洋的三维观测中补充被动海洋颜色遥感。本文介绍了舰载多视场（MFOV）激光雷达的设计和验证。通过同时输入原位数据，可以使用模拟结果对激光雷达信号和所获取的激光雷达衰减系数α进行定量验证。仿真方法包括准单散射激光雷达方程，蒙特卡罗（MC）方法和解析模型。实验激光雷达信号与模拟激光雷达信号一致，确定系数R ² > 0.91，并且从实验激光雷达信号中检索到的α与相对误差δ <0.18的均方根（RMS）的模拟值非常吻合。不同视场（FOV）的结果表明光束衰减系数c，扩散衰减系数K _d和α之间的关系。这项工作有利于研究海洋激光雷达的机理，检索和应用。
