摘　　要：根据昆虫利用天空中偏振光导航的仿生原理,构建了偏振导航传感器的模型,分析了该模型测量原理,并对模型中影响测量精度的误差源进行了分析计算,结果表明偏振度、有效光强以及两偏振光轴间的相对角度误差会影响系统的测量精度和灵敏度。这一结论对偏振导航传感器的应用具有指导意义。Based on the bionic principle of insect navigation using polarization light, the model of polarization navigation sensor was built; the measuring principle of model was analyzed in detail. Various factors affecting the measuring accu- racy were analyzed and calculated. The simulation was carried out to validate the above mentioned analysis. The results show that the measuring accuracy and system sensitiveness can be influenced by polarization degree, effective light intensity, and relative angle between polarization light axes. The conclusion can be a reference for application of polarization navigation sensor.
