Abstract: An orienting method is proposed for bionic navigation with the polarized light patterns. Combining theoretical analysis with experiment, authors build a kind of theoretic and experimental models. Then the sun’s relative position and a navigation reference line (solar meridian) are derived details for navigation system to provide orientation information. Finally, based on the horizon coordinate system, an example is given for the whole calculate process of direction angle.

Key words: polarized light, solar meridian, navigation coordinate, direction angle

摘要： 提出了一种利用天空偏振光分布确定仿生导航系统航向角的方法。该方法将理论分析和实验相结合，建立了天空偏振光分布的理论和实验模型；在深入分析模型的基础上，确定了为导航系统提供航向信息的导航参考线??太阳子午线；结合天文导航方法，确定太阳的相对位置。最后，建立地平坐标系为导航坐标系，举例说明了确定航向角的整个过程。
