| 摘 要： | 通过理论推导得到了竖直方向上白天天空背景光光强计算公式。根据激光雷达30km处的瑞利数据反演了30km以下的大气透过率,利用反演出的大气透过率和推导的背景光计算公式,计算了天空背景光的白天变化,与实测数据符合较好。同时也说明了白天用FADOT窄带激光雷达探测有限距离大气透过率的可行性。

| Abstract: | The function of background irradiance at vertical direction in daytime is obtained through theoretical analysis.The atmospheric transmission under 30km is computed according to the lidar returns at 30km.The background irradiance which is countod out by using the atmospheric transmittance matching up to the measured one is well.The feasibility of to measure atmospheric transmittance by using FADOF lidar is testified. |
