Abstract

Infrared Polarization imaging possesses the ability of distinguishing between natural objects and man-made objects. However, the reflection and radiation of the sea surface and the target have strong infrared polarization characteristics, which makes it difficult to detect the ship's target with infrared polarization. Based on the bidirectional reflectance distribution function model, stokes parameters and Cox model, we analysed the process of the ship-target and environment radiating and reflecting, deduced the mathematical model of target and sea’s degree of polarization(DOP) .Comparing the reflection and radiation distribution curves at the large zenith angle, the polarization characteristic of the target background reflection radiation is obtained, the experiment shows that the correctness of the mathematical model and conclusion. The result of this paper provides a good opportunity for further research on the polarization recognition of ship-targets.
