Symmetry in a target gives related properties to the electromagnetic scattering. Emphasizing targets on or below the surface of the ground (or water), this paper considers symmetry in the context of magnetic singularity identification (utilizing low-frequency diffusion in metal targets) and electro-magnetic singularity identification (utilizing a ground-penetrating radar with wavelengths of the order of the dimensions of the metal and/or dielectric targets). It is found that the presence of various target symmetries can be detected and that this can potentially be used as a target discriminant (a first-order cut) for concentrating ones attention on more interesting targets (for further analysis and/or destruction).
