摘要: 该文提出了一种基于图像熵变化及窗口能量检测的探地雷达自动目标检测与定位方法,该方法首先通过探地雷达未经合成孔径处理的图像与经合成孔径处理后的图像之间的熵变化来检测目标,再通过在合成孔径图像中进行窗口能量检测来判断目标所在的位置。通过对实测数据的处理,结果表明该方法取得了较好的效果。Abstract: This paper proposed a new automatic target detection and orientation method based on image entropy variation and window energy detection. This method decides whether target is existing by the variation of entropy in ground penetrating radar image before synthetic aperture processing and after synthetic aperture processing, then decides the location of target by detecting window energy in ground penetrating radar synthetic aperture image. The results of processing measurement data show this method is effective.
