| 摘 要： | 进行低空探测的机载激光雷达消光系数反演存在着标定点选取和标定值确定两大困难.Fernald迭代后向积分法能够在不利用其它辅助没备的情况下,找到进行低空探测机载激光雷达消光系数反演所需的标定点和标定值.利用Fernald迭代后向积分法和Palm et a1.(2002)方法分别对青岛机载激光雷达实验数据进行处理,得到的两条消光系数廓线基本吻合.定蜃分析显示:利用Fernald迭代后向积分法进行机载激光雷达消光系数反演时,激光雷达比对消光系数反演结果影响很大;标定点的消光系数值及迭代判据的取值对机载激光雷达消光系数反演的结果影响较小.Fernald迭代后向积分法为不用其它辅助设备进行低空探测的机载激光雷达消光系数反演提供了一种可行的范例.

| Abstract: | It is difficult to determine gauge point and calibration value in extinction coefficient inversion of airborne lidar that detects in low altitude.Fernald iterative backward integration method can find gauge point and calibration value for extinction coefficient inversion without other auxiliary equipment when airborne lidar is used for low altitude detection.Airborne lidar data of Qingdao is disposed using Fernald iterative backward integration method and Palm et al.(2002),and two extinction coefficient pro... |
