首先基于偏振探测原理，提出一种利用地物偏振信息识别伪装目标的方法。然后研制了一套多光谱偏振探测系统，并编制了相应的图像处理软件。最后利用该系统在400∼1000 nm波段内对林地型背景中的铁板和迷彩伪装板进行了多光谱偏振探测实验。图像处理结果表明：地物背景和迷彩伪装板的偏振特性各不相同，与自然背景相比，伪装目标的偏振特性非常显著，利用偏振探测技术能够凸显背景中的伪装目标，提高目标探测和场景识别的准确度，相对传统的光强探测更容易从杂乱的背景中实现对伪装目标的有效探测与识别。%By analyzing the principle of polarization detection, a method that was applied to recognize camouflage targets with their polarization information was presented. A multi-spectral polarization system was designed and the processing software was programmed. Then the experiment about the iron plate and camouflage plates placed on typical woodland background were conducted by the system at 400∼1 000 nm. The results of image processing and analysis indicate that the polarization characteristics of camouflage plates and background are different. By comparing with natural background, the polarization characteristics of camouflage plates are obvious. The result shows that the classical camouflage target can be detected and identified effectively by the spectral polarization technique. Consequently, compared with the traditional intensity detection, the spectral polarization detection technique is of significance to improve the veracity of detection of camouflage targets in mixed background.
