Detection of buried landmines by ground penetrating radar (GPR) normally
suffers very strong clutter that will decrease the image quality in
GPR data. Problems are also encountered when imaging steeply dipping
landmines by GPR. To solve these problems, we have developed a steppedfrequency
continuous-wave array antenna ground penetrating radar system,
called SAR-GPR, that can acquire common middle point multi-offset data. As
an approximate solution to the general wavefield inversion problem, migration
algorithms were used to refocus the scattered landmine information to improve
signal–clutter ratio and re-construct the landmine image. Also, pre-stack
migration was found to efficiently deal with the steeply dipping landmine
