Abstract

Artificial target has the characteristics of stronger polarization, which is found in the process of researching polarization remote sensing. So the polarization characteristics of artificial target has become one of the highlights in the research of the polarization remote sensing. Metal coating target is a kind of typical artificial target, previous studies have found that metal coating target polarization reflection characteristics vary with the condition of different observation angle and incidence angle, and the difference of polarization characteristics greatly impact the derivation and accuracy of metal material surface. In order to research the characteristics of metal coating surface bidirectional reflectance polarization, this measurement experiment set up four observation azimuth angle and nine observation zenith angle .On the basis of the measured data by using the semi-empirical model for data fitting, then get the data of metal coating target hemisphere space distribution of polarization reflection characteristics . This paper analyzes the relationship between target surface polarization degree and observation azimuth angle, observation zenith angle, which provides theory and data support for the derivation of typical artificial target structure features.
