Determination of overlap function is a key step in the calibration of a high-spectral-resolution lidar (HSRL). In this work, an iterative-based general determination (IGD) method for overlap function in HSRL is proposed. Error analysis with Monte-Carlo (MC) simulation is performed and illustrates the algorithm shows high accuracy and has high stability with an accurate lidar ratio assumption. A comparison experiment shows the overlap function from the proposed algorithm agrees well with that from a dual-field-of-view (dual-FOV) HSRL system. Since no modified optical system in HSRL is needed, this method shows great potential in real-time recording of overlap function in the HSRL system.

ZJU气溶胶和云雾高光谱激光雷达的开发:重叠功能的校准

重叠功能的确定是校准高光谱分辨率激光雷达(HSRL)的关键步骤。在这项工作中,提出了一种基于迭代的HSRL中重叠函数的通用确定(IGD)方法。进行了蒙特卡洛(MC)仿真的误差分析,并说明了算法的准确性和激光雷达比的假设,该算法显示出很高的准确性和稳定性。对比实验表明,该算法与双视场HSRL系统的重叠函数吻合良好。由于HSRL中不需要修改的光学系统,因此该方法在HSRL系统中重叠功能的实时记录中显示出巨大的潜力。
