摘　　要：大气光学偏振模式中包含了丰富的方向和位置信息,通过有效提取和利用大气偏振模式信息,可以实现一种全新概念的自主导航定位方式。E-矢量是其偏振信息中最为关键和最为稳定的参数,仿照昆虫的导航偏振敏感机理,设计了一种仿生复眼光学偏振传感器;根据昆虫的POL-神经元的信号处理方式,推导出传感器输出信号数学处理方法;对传感器进行了测试实验并在不同天气下对大气偏振模式中E-矢量方向进行检测。通过对晴朗无云的天气大气偏振模式进行检测,偏振E-矢量平均误差为0.467 52°。对大气E-矢量的检测表明仿生复眼光学偏振传感器能够实现对大气偏振模式的准确检测,为偏振光导航这一自主导航系统发展奠定了基础。Atmospheric optics polarization pattern contains abundant direction and position information, a brand new concept of autonomous navigation mode can be achieved through the acquisition of atmospheric polarization pattern, among whose polarization information E-vector is the most important and stable parameter. According to the mechanism through imitating the polarization sensitive mechanism of insects, a polarization sensor based on bionic compound eyes was designed ;according to the signal processing method of insect＇s POL-neurons, the mathematical processing method of the output signal of the sensor was deduced;test and the monitoring of E-vector are carried out. Through detecting the atmospheric polarization pattern in the sunny days, the average error of the sensor is 0. 467 52°. Experimental results of monitoring of E-vector indicate that the bionic polarization sensor can monitor at- mospheric polarization pattern precisely, laying the foundation for an autonomous navigation system based on polarized light.
