摘　　要：提出了一种利用目标的偏振信息识别人造目标的新型方法。利用自制的多波段偏振CCD地面实验装置获取目标的偏振图像,并提取其中的偏振信息。由于人造目标和自然目标的偏振特性上有较大差别,因而根据这些信息,通过较常规的图像处理手段,即可很好地识别出图像中的人造目标。实验证明,该方法识别自然背景下的人造目标是相当有效的。A novel scheme that is applied to recognize manmade objects with their polarization information is presented. Polarization images of objects are obtained by the self-made multi channels CCD polarimetric instrument. The polarization information is extracted. Because of the difference between the polarization characters of natural objects and manmade objects, the manmade objects can be well recognized by means of general image processing approaches. With experiments, it turns out that the method is effective in separating manmade object from natural background.
