中文摘要：
单点偏振光导航方法只能检测部分天空区域的大气偏振模式,所获取的导航信息依赖于观测位置,具有一定的局限性。通过模仿沙蚁感知偏振光并解析航向信息的3个层次,即小眼阵列对偏振信息的接收、POL-神经元的信息响应以及大脑神经元的航向计算,设计了一种仿沙蚁神经处理机制的偏振光导航信号处理模型,实现了全天域大气偏振模式的E-矢量分布与航向信息之间的映射。开展了模仿沙蚁导航行为的仿真实验,结果表明,该模型验证了沙蚁感知偏振光并解析航向角的信号处理机制,为偏振光导航传感器的设计提供了新的思路。
英文摘要：
The method of point-source has some limitations due to it can only detect the atmospheric polarization pattern information in a partial region and the navigation information depends on the observation location.This paper proposed a computational model of polarization light navigation inspired from the neural mechanism of Cataglyphis through three arrangements included the reception of polarization information of small eye array,the response of POL-neurons,and neuronal course computation.The model realized the mapping of the atmospheric polarization pattern of all regions and the orientation information.Also,different simulation experiments on imitate Cataglyphis＇ navigation behavior are carried out,the results show that the proposed model efficiently verifies biological processing mechanism of polarization light navigation and provides a new idea for design of polarization light navigation.
