| Abstract: | A new method of pattern recognition is presented in this paper.The method can identify the typical object such as bridge from synthetic aperture radar image.First, constand false alarm rate processing is applied to the SAR image, in order to exclude obvious non target area and enhence the effect of recognition. Then the method of direction ratio is used to process bridge target. After the method of direction ratio, the method of bilateral parameter are adopted to process bridge target,achieve a better result. |
