| 摘 要： | 介绍了热红外偏振测量的原理，采用利用偏振信息在红外图像中识别伪装遮障的方法研制了一台热红外偏振成像仪，编写了偏振信息分析软件。利用该系统对地物背景（土壤）中的不同种类金属目标板及红外伪装遮障进行了热红外偏振成像探测实验。结果表明：在利用热红外偏振探测系统获得的Stokes矢量图中， 地物背景、金属目标板及红外伪装遮障的热红外偏振特性各不相同，并且和其红外辐射强度无关，相对红外强度探测更容易从地物背景中识别出金属目标板及红外伪装遮障。

| Abstract: | By analyzing the method of thermal emission polarization detection, a method that is applied to recognized camouflage nets with their polarization information in thermal images is presented. A thermal imaging polarization system is designed and demonstrated.The Stokes parameters images of metal objects and camouflage nets in earth background are acquired by the thermal imaging polarization system in experiment. Experimental results show that the polarization characters of metal objects, camouflage nets and earth background are different. These polarization characters have no relationship with their emitted radiation intensity. This method is effective in recognizing metal objects and camouflage nets from natural background. |
