The finite difference frequency domain is used to study the scattering of buried non-metallic mine-like targets to determine the feasibility of identifying mines form shape features. It is shown that for constant cross-sectional target area - approximately 100 cm2 - the scattered fields of targets with roughly the same height-to-width aspect ratio at 500 MHz are virtually indistinguishable regardless of burial depth. A comparison of the field obtained for mine-like targets of different aspect ratios, but with constant area, buried at a depth of 5 cm, shows marked differences, as does scattered field for GPR frequencies above 700 MHz. The conclusion of this study is that while low GPR sensing frequencies may help to detect shallow anomalies, they do not supply any useful information about the shape details - particularly the edges - of the buried non-metallic mine-like targets.
