Development of ZJU high-spectral-resolution lidar for aerosol and cloud: calibration of overlap function
2020
Abstract 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.
