摘　　要：通过分析信号光、背景辐射光的偏振特性,给出信号光和背景辐射光偏振态的异同,利用偏振探测技术最大化的抑制背景辐射噪声,提高激光雷达系统的信噪比、探测距离。Through analyzing the polarization of signal light and background radiation light, the difference of their polarization states was found out. Then the polarization detection technology was used to maximize suppress the background radiation noise. As a result, the laser radar system′s SNR and the detection distance were improved.

关 键 词：背景辐射噪声 偏振度 散射
