Research on Automatic Target Detection and Orientation of Ground Penetrating Radar in Shallow Subsurface Application

摘要: 該文提出了一種基于圖像熵變化及窗口能量檢測的探地雷達自動目標(biāo)檢測與定位方法,該方法首先通過探地雷達未經(jīng)合成孔徑處理的圖像與經(jīng)合成孔徑處理后的圖像之間的熵變化來檢測目標(biāo),再通過在合成孔徑圖像中進行窗口能量檢測來判斷目標(biāo)所在的位置。通過對實測數(shù)據(jù)的處理,結(jié)果表明該方法取得了較好的效果。

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. -
