Study on the buried object detection method using optimum frequency range method in extremely shallow underground

Sound wave vibration and a scanning laser Doppler vibrometer (SLDV) are used for a method of exploring and imaging an extremely shallow underground. In this study, the optimum frequency response range method (OFR method) is proposed for detecting the buried object and forming the clearest image. From the experimental results, we can confirm that the buried object can be detected by the OFR method and, compared with before applying the OFR method, we can see that the effect of the noise is decreased by the OFR method. As a future task, we will examine the effectiveness of our method for other materials.
