| 摘 要： | 提出了一种浅层探地雷达快速异常区域检测方法.通过数字图像处理技术对探地雷达探测数据进行分析处理,根据地表回波梯度幅度大的图像特性将其从雷达数据中去除以克服其对地下异常目标检测的影响,然后利用基于梯度的自适应阈值方法在抑制杂波干扰的同时,对地下层中的异常区域进行快速定位.通过实测数据的实验验证,证实了所提的方法在处理异常目标检测与定位时的高效与快速.

| Abstract: | A fast abnormal target detection method for shallow ground penetrating radar (GPR) is developed. Digital image processing method is used to analysis the data from the GPR. According to ground echo component with high gradient variation, it is removed from the GPR data to overcome its effects on detection of abnormal target at first. A gradient based adaptive threshold selection is used to suppress noise distribution and to make a quick detection for the abnormal target regions. Experimental results show tha... |
