Paper Abstract
We consider migration based synthetic aperture radar (SAR) imaging
of surfaced or shallowly buried objects using both down-looking and
forward-looking ground penetrating radar (GPR). The well-known
migration approaches devised to image the interior of the earth are
based on wave equations and have been widely and successfully used
in seismic signal processing for oil exploration for decades. They
have exhibited great potentials and convenience to image the
underground objects buried in complicated propagation medium.
Compared to the ray-tracing based SAR imaging methods, the migration
based SAR imaging approaches are more suited for the imaging of the
underground objects due to their simple and direct treatment of the
oblique incidence at the air-ground interface and the propagation
velocity variation in the soil. In this paper, we apply the
phase-shift migration approach to both the constant-offset and the
common-shot experimental data collected by the PSI (Planning Systems
Inc.) GPR systems. We will address the spatial aliasing problems
related to the application of migration to the GPR data and the spatial zero-padding approach to circumvent the problem successfully.
