Polarization remote sensing is a new method with several advantages in detection. It is very important to study atmosphere and targets on the ground. To investigate the polarimetric scattering characteristics of camouflage targets, polarimetric parameters of three color pattern camouflage net were measured in visible and infrared waveband. By the analysis of data, it was found that polarimetric scattering characteristics of camouflage net were mainly influenced by incidence angle and reflectance of surface under a definite detecting condition. The polarization degree of scattering light goes up with the increase of incidence angle and falls when the reflectance of surface rises. The imaging of polarization degree can enhance the brightness and contrast of low reflectivity pattern, and the imaging of polarization angle is very sensitive to the outline of camouflage net. Polarization remote sensing is very useful to the detection of low reflectivity targets in complex backgrounds and threatens the existence of camouflaged military targets badly.
