中文摘要：
针对同时存在方位偏移及俯仰误差的情况,提出了一种适用于捕获、对准与跟踪系统的光斑检测方法.分析了破碎光斑与高斯完整光斑的位置误差;解决了当光束存在漂移、入射光束与天线视轴不平行同时存在而四象限探测器无法分别探测的问题.最后实验验证了本文方法的有效性,提高了检测的准确度.
英文摘要：
A spot detection method was proposed for acquisition,pointing and tracking system in the case of azimuth offset and pitch errors exist at the same time.The position error between the broken spot and the Gaussian complete spot was analyzed.The problem was solved when the beam was drifted and the incident beam was not parallel to the line of sight of the antenna and the four-quadrant detector could not be detected separately.In the end,conduct experiments to verify the validity of approaches.The improvement of detection precision is also presented.
