【摘要】 信号跟踪是空间光通信ATP技术研究的主要内容之一。在自然背景条件下,由于环境噪声和背景噪声的干扰,使激光信号的跟踪变得困难。文中介绍的算法能在自然背景条件下,结合帧差法与阈值化方法自适应地跟踪激光信号,并通过实验验证了算法的有效性与稳定性。更多还原

【Abstract】 Signal tracking is one of the researches of ATP (acquisition,tracking,pointing) technology for free-space optical communication (FSO). Tracking laser signal is very difficult under natural background condition due to the interference of environment and background noises. To self - adaptively track the laser signal under background condition, a new algorithm combined with frame subtraction algorithm and thresholding algorithm is proposed. The experimental results prove the availability and stability of the new algorithm.更多还原
