“…S1 summarizes the four major approaches to achieve spectral and polarization detection. The first approach is to place separate optical components such as interference filters or wire-grid polarizers in front of the detectors [1][2][3][4]. The second approach is to take advantage of the intrinsic spectral and polarization selectivity of certain photosensitive materials [5][6][7][8][9].…”

“…They founded that there isobvious differences between military artificial target and natural background polarization characteristics, thus polarization imaging can distinguish different objectives and background, as shown in Figure1. (ARL) carried out the Spectral and Polarimetric Imagery Collection Experiment (SPICE) in February 2010 [3] . They had measured the polarization characteristics of Russian auto-howitzer for seven months.…”

Polarization is a primary characteristic of electromagnetic wave. Polarization is another field of the light except the intensity, wavelength, and coherence. Polarization can indicate the different attributions that decided by objects, such as surface features, roughness, shading, shape and so on. Polarization Imaging is a useful complement to traditional intensity and spectral imaging methods with great potential in many application fields. In the future war, the advantages of polarization are significant for target detection and recognition in the increasingly complicated battlefield environment. In this paper, the research progress is generally introduced in military application in four fields: 1) target polarization characteristics and simulationenhance contrast, distinguish the target and background; 2) polarization transmission characteristics-observe target through the smoke and fog of War; 3) polarization imaging detection methods-improve the imaging quality, enhance the information available; 4) polarization image processing-improve detection and tracking performance.

“…In the same year, Egan 13,14 of New York University used a focal plane polarization camera to compare and analyze the polarization images of 9 positions on C-130 camouflage aircraft in 5 different sky backgrounds, and the results showed that the polarization reflection characteristics of natural background and camouflaged targets were quite different, and the camouflaged military targets could be well detected by polarization detection. Since February 2010, the U.S. Armament Research, Development, and Engineering Center (ARDEC) and the U.S. Army Research Laboratory 15 have jointly carried out the spectral and polarimetric imagery collection experiment, using the hyperspectral, polarimetric, and broadband sensors to automatically collect the mid-wave and long-wave infrared imagery of 2S3 Self-Propelled Howitzer for seven months at all hours, all-weather and from multiple angles. Sun et al mainly focused on the polarization characteristics of snow 16,17 , leaf 18,19 , and soil 20,21 , and analyzed different influence factors.…”

The target polarization characteristics reflect the important information about the medium material, surface texture, and structural characteristics of the target itself. In this paper, 9 kinds of samples with different materials, roughness, and surface texture direction are selected to measure the polarization characteristics in an outdoor environment, and the influencing factors of the target polarization characteristics are analyzed, where the influence of the surface texture direction on the spatial distribution of the target polarization characteristics is emphatically analyzed. The results show that the target polarization characteristics are affected by many factors such as material, roughness, surface texture direction, and detection position, and the greater the angle between the surface texture direction and the principal plane, the more concentrated the target polarization characteristics are in and around the principal plane, which could provide a theoretical basis for comprehensively mastering the target polarization characteristics, improving the ability of target polarization detection and recognition, and enhancing the confidence of the target polarization modeling and simulation.
