A method for subsurface metallic landmine identification in GPSAR

A method for subsurface metallic landmine identification in Air- or vehicle- borne ground penetrating synthetic aperture radar (GPSAR) using finite difference time domain method combined with genetic algorithm is proposed. To identify the real object, the framework information on landmine is obtained according to the matching algorithm based on number and relative location of one dimensional scattering center. By identifying two kinds of metallic landmines buried beneath a Gaussian rough interface, the effectiveness of the proposed method is testified. Electromagnetic modeling result will improve the landmine detection performance greatly.
