In surface mapping synthetic aperture radar (SAR), homogeneous media is usually assumed, through which transmitted and reflected signals propagate. In ground penetrating SAR (GPEN SAR) system designed for detecting buried targets, we must take account of multiple media condition. It brings several factors which affect the quality of SAR image, such as refraction on air-soil interface and wave attenuation in the soil. These effects will be quantitatively analyzed in this paper. Also some simulation results show the comparison between surface target image and buried target image.
