由于大气效应和目标相对运动的显著影响，获取、指向和跟踪（APT）是自由空间光通信（FSO）中建立通信链路的关键技术。本文提出了一种全向圆柱形光学天线，重点研究了波束控制的理论和方法。在通信终端随机移动和天线自变速或匀速旋转的情况下，进行了数值模拟。详细分析了实际应用中的一些重要参数，如通信时间、实际带宽和中断时间，并与理论结果进行了比较。结果表明，波束控制方法是可行的，该光学天线在一定高度范围内能够满足快速移动FSO的要求。(c) 2012 Elsevier Ltd.版权所有。
Due to the notable influence of atmospheric effects and the objects relative motion, acquisition, pointing and tracking (APT) are the key technologies to establish the communication link in free space optical communication (FSO). In this paper, an all-direction, cylinder-shaped optical antenna is proposed, and the theory and method of beam control are mainly studied. On condition that the communication terminals move randomly and the antenna self-rotates in constant or variable velocity, numerical simulations are carried out. In detail, some significant parameters in practice are analyzed, like the communication time, actual bandwidth and interrupted time, and compared with theoretical results. The consequence shows that the beam control method is feasible, and this optical antenna can meet the demands of fast mobile FSO in a certain range of height. (c) 2012 Elsevier Ltd.
