Polarization is an important feature addition to the wavelength, amplitude, phase of electromagnetic waves. Use different polarization properties of the material can provide more dimensions of information for the detection and identification of targets. Based on the theory of polarized imaging,we design a simultaneous polarimetric imaging instru-ment and set up a common imaging system for comparison. After system has been encapsulated,the field experiment is carried out, and the images acquired by the polarization imaging system are processed by image fusion. The target's contrast is improved by 28% compared with the ordinary imaging system,which shows the advantage of polarization im-aging in recognition-target.%偏振是电磁波的重要特征,是光除了波长、振幅、相位以外的又一重要属性.利用物质的不同偏振属性能够为目标的探测和识别提供更多维度的信息.基于偏振成像理论设计了同时偏振成像仪器,并设置了用作对比的普通成像系统.在对系统完成封装后进行了外场的实验,将偏振成像系统获取的图像进行图像融合等处理,目标对比度相比于普通成像系统提升28%以上,体现出了偏振成像在识别目标上的优势.
