摘　　要：介绍了分孔径发射 /接收 5 3 2nm脉冲激光雷达实验装置 ,分析了不同条件下背景噪声对脉冲激光雷达成像的影响 ,讨论应用时间选通技术和频谱滤波技术对背景噪声的抑制效果 ,通过实验研究了小视场条件下工作距离、发射激光能量及能见度之间的关系。532 nin pulse imaging lidar experimental equipment was introduced. Both the effects of background noise and the signal-to-noise of 532 nm pulse lidar system under different conditions were analyzed. The relationship of distance, pulse-energy and visibility under narrow view-angle was researched by experiments.
