Focusing ground Penetrating Radar images with vertical offset filtering

Existing focusing techniques for Ground Penetrating Radar (GPR) rely on migration of 2D or 3D images to remove clutter originating from objects laterally ofiset from the antenna. In applications requiring real-time focusing, a method operating on 1D trace data is required. This paper presents a new algorithm for focusing GPR images, the Vertical Ofiset Filter (VOF), using simulated and real GPR data.
