合成孔径雷达图像中桥梁形状的目标识别

The identifying of typical target on the SAR image

识别 SAR图像中桥梁形状目标 ,先对 SAR图像进行预处理 ,排除明显的非目标区 ,增强对目标的识别效果 ,然后在此基础上进行针对桥梁形状目标的处理 ,包括方向比值法和双边参数法 ,可得到较好的识别效果。

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.
