地中探査レーダのための逆投影ヒストグラム法による画像再構成

抄録

The aim of this research is to improve a horizontal resolution of microwave subsurface radar. A back projection histogram method is newly proposed as imaging process from measured waves. This method consists of two phases; imaging process and superposition process. In the imaging process, back projection images are constructed from each reflected wave on concentric circle with center at measurement point. Multiple back projection images are superimposed in the superposition process. Experimental results on two steel pipes detection show that the horizontal resolution is improved by proposed method.
