Subsurface CW interference radar
Electronics Letters, 1995 A new subsurface CW (continuous wave) interference radar having the great advantage of detecting a fine shallow target is presented. The horizontal location of the target submerged in a dissipative half-space may be detected easily by using the symmetry of the measured electric field pattern.
