基于脉冲激光和大气作用的散射效应，搭建了实验平台，进行了散射激光的前向、后向、侧向捕获与测量。实验结果表明：前向散射效应较强，约为后向散射的几十倍。随着散射角增大，散射效应急剧下降，接近垂直方向时，侧向散射效应表现很弱。设计的光电探测组件、接收放大模块、基于A RM 处理器的同步分析与处理系统满足对序列激光脉冲同步处理的要求。
基于脈遲激光和大氣作用的散射效應，搭建瞭實驗平檯，進行瞭散射激光的前嚮、後嚮、側嚮捕穫與測量。實驗結果錶明：前嚮散射效應較彊，約為後嚮散射的幾十倍。隨著散射角增大，散射效應急劇下降，接近垂直方嚮時，側嚮散射效應錶現很弱。設計的光電探測組件、接收放大模塊、基于A RM 處理器的同步分析與處理繫統滿足對序列激光脈遲同步處理的要求。

Based on the scattering effect of pulse laser in atmosphere ,the corresponding experi‐mental platform was set up .Experimental measurements of forward ,backward and lateral scattering were carried out .The experimental results and theoretical analysis were basically identical .Forward scattering effect was dozens of times stronger than that of backward scattering .With the increase of scattering angle ,the scatting effect decreased sharply .Lateral scattering effect became very weak as close to vertical direction .The photoelectric detection module ,receiving amplifier module ,the syn‐chronization analysis and processing system based on ARM processor met the requirements of the se‐quential laser pulse synchronization processing .
