Detailed Description

机载激光扫描测距仪及其性能分析模型

江月松,李树楷:机载激光扫描测距仪的性能分析。遥感学报,1998, 2(3)

1)激光脉冲信号功率模型:

式中,为发射的激光能量;为激光脉冲宽度;为接收器面积;为激光器到目标表面的距离;为光学系统透射率;为云层的透射系数;为双程大气溶胶透射率;为系统充满系数;为目标的后向散射率。

2)噪声功率模型:

式中,为在1.047nm波长处大气引起的太阳光谱辐射;为接收器的视场角;为接收系统的透射率;为接收器的窄带通滤光片。

(1)综合信噪比知R模型:

式中,Si APD的增益;Si APD的额外噪声因子;为探测器带宽。
