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
