Atmospheric polarization pattern includes significant information

which is caused by the sunlight scatterning during the process of transmission.Many insects gain directional information using the atmospheric polarization pattern.According to the insect biological mechanism of detecting polarized light and decoding polarization information

a network model which imitated insects polarization-sensitive neurons is researched.The network is used to process the signal of bionic polarization compass by simple math computation.Simulation result shows that this signal processing method can accurately obtain compass direction.
