摘要

利用大气后向散射几何模型

推导出后向散射的累积效应的近似表达式。计算结果表明

50 m范围内的后向散射光占光学系统可接收到后向散射光通量的80%。针对近距离后向散射光的上述特点

提出了采用双通道光学接收系统处理后向散射光的方法。软件模拟结果证明

该方法具有较好的后向散射光抑制效果

系统结构设计简单、容易实现。

Abstract

According to geometry model of the atmosphere back-scattering

an approximately expression of atmosphere back-scattering accumulative effect was deduced in this paper. The result showed that 80% of the backscattered flux of the receiver come from those particles inner 50 m away from the receiver. Then

a new method of dealing with the backscattered light was presented by using a double passage optical receiver. The simulation result proved its good effects in improving image quality. The construction of the double passage receiver was simple and it can be easily realized.
