According to the experimental result of an altazimuth, it has been proved that Support Vector Machine is superior to Neural Network in the recognition of the intermittent failure under the small training samples, and the BIT false alarm caused by environmental factor can be effectively reduced by this means.

某型号航空地平仪的试验结果分析表明：在小训练样本的情况下，支持向量机比神经网络具有更好的间歇故障识别能力，能够有效地降低由环境因素引起的虚警。

The physical model of polarizing beam coupling and splitting system using altazimuth coude telescope is built up based on Mueller matrix and Stokes vector. The phenomena of the decreasing of the receiving efficiency are successfully explained by this model. Three dynamic phase compensation solutions are proposed: 1 Two quarter-wave plates are rotated to compensate the phase of the laser.

针对这个问题，建立了地平式折轴望远镜的共孔径偏振耦合分光模型，用Stokes矢量和Mueller矩阵分析了在望远镜旋转过程中激光偏振态的变化，数值模拟计算了望远镜处于不同方位角和天顶角时的偏振耦合分光效率，解释了实验中观察到的望远镜旋转导致偏振耦合分光效率退化的现象。
