Abstract

In order to identify the camouflage materials in military targets, this paper extracts multiple features to study the difference in optical characteristics between natural targets and man-made camouflage materials. Since Fresnel reflection can be regarded as a statistical description of scattering, this paper uses a multi-angle polarization measurement device to measure polarization and scattering characteristics. According to the physical meaning of the Mueller-Jones matrix, the expressions of amplitude ratio and phase retardation are extracted. Based on Pauli decomposition, new scattering similarity parameter formulas is defined. We discuss the curves of three characteristic parameters and analyze the difference between natural objects and camouflage materials. The experimental results show that the characteristic curves change significantly at Brewster’s angle, which clearly distinguishes the target from the camouflage material.
