Abstract: Polarimetric parameters and polarization imaging of camouflage net were measured to study the effect of polarization remote sensing on the camoulflage targets.It is found that the polarization degree of camouflage net was greatly influenced by the condition of detection and characteristics of materials, such as reflectance, refractive index and roughness of surface. The interaction between incident light and camouflage coating can be divided into two parts, surface scattering and volume scattering. Surface scattering act as a function of polarization and volume scattering act as a function of depolarization.The polarimetric characteristics of camouflage targets were different from natural background. Compared with traditional remote sensing, polarization remote sensing can find the camoufl
