摘　　要：基于CCD的角度偏差检测技术,对深空光通信中扩展信标的捕获机制进行了实验室模拟演示实验研究,获得了较好的演示效果。对实验结果分析表明,对应不同的捕获分辨角,实验得到的捕获概率与理论分析结果呈现相似的变化趋势,同时对捕获完成后系统的瞄准误差进行分析,结果表明瞄准误差在3个像素以内,并分析了误差产生的原因。Extend-beacon optical communication based acquisition demonstration experiment in laboratory for deep space on CCD angle monitor technology was executed. Perfect demonstration purpose was gained. The result shows that the variation rules of the experimental and theoretic acquisition probability corresponding to variational acquisition differentiation angle resemble. Meanwhile, the pointing error after acquisition finished was analyzed. The result shows that the pointing error is below 3 pixels, and the reasons for pointing error are also analyzed.
