In order to improve the target identification capability of the anti-tank missiles, the difference in polarization properties of the target and the background can be utilized to realize target detection and recognition.The intensity images and polarization images of the armored vehicles in four different environment backgrounds, such as no background, grass background, concrete background, and sandy background, are obtained by using the active laser polarization imaging technology. All these acquired intensity and polarization images are compared and analyzed in terms of edge intensity, image definition and spatial frequency, respectively. The results show that the polarization images have better edge and detail characteristics than the intensity images, which is conducive to the vehicle target recognition under complex background. The active laser polarization imaging technology will play an important role in promoting the target recognition capability of anti-tank missiles.
