红外偏振成像在伪装目标识别中的应用研究

红外偏振成像技术可以提高探测伪装或隐身目标的能力。作为对抗红外隐身的侦察手段，它已成为国内外研究的重要内容。通过分析红外偏振成像的进展，提出将红外偏振成像技术应用于目标检测。为了研究伪装目标的偏振散射特征，利用红外偏振成像系统对覆盖和未覆盖军用三色迷彩伪装网的目标场景进行了探测研究。研究发现，红外偏振成像可以作为探测伪装或隐身目标的新途径，其成像效果较好。此外还证明偏振探测技术对复杂背景中低反射率伪装目标的独特识别优势在中红外波段同样成立，而且偏振角成像对伪装网的外形特征非常敏感。

Application of Infrared Polarization Imaging in Camouflage Detection

Infrared polarization imaging can improve the ability to detect camouflage or stealth targets. As a reconnaissance means against infrared stealth, the infrared polarization imaging technology has become an important research content at home and abroad. By analyzing the progress of infrared polarization imaging, the infrared polarization imaging technology is suggested to be used in target detection. To study the polarization scattering characteristics of camouflage targets, an infrared polarization imaging system is used to detect the target scenes with and without three-color camouflage nets. It is found that the infrared polarization imaging can be used as a new approach to the detection of camouflage or stealth targets and it has a good imaging result. In addition, the research shows that the unique advantage of polarization detection in recognition of camouflage targets with low reflectivity against complex background is also valid in the mid-infrared wavelength band. Moreover, the polarization angle imaging is very sensitive to the external physical characteristics of camouflage nets.
