Modeling of Metallic Landmine Electromagnetic Characteristic in GPSAR

摘要：

Air-or vehicle-borne Ground Penetrating Synthetic Aperture Radar (GPSAR) has the capability to detect subsurface objects over large area from a standoff distance quickly.Inorder to reduce the false alarmsInobject detection,it is needed the design efficient detector on the electromagnetic characteristics between mines and clutter.A method on analyzing electromagnetic characteristic on subsurface objects using FDTD method combined with Fourier transform is proposed. We model the time-domain scattered field of metallic landmine buriedInsoil. Numerical results fit the data computed by moment method.Finally,we model the M6A1 metallic landmine buried in soil.Numerical results fit real data based on actual measurement.Electromagnetic modeling result will improve the landmine detection performance greatly.
