Patent ID: 8854247

Claim:
A ground penetrating radar (“GPR”) and metal detector (“MD”) hybrid head comprising: an MD sensor including at least one receive coil in a quadrupole configuration including a crossbar, and at least one transmit coil, the crossbar having a first axis parallel to a direction in which current flows in the crossbar; and at least one GPR V-dipole antenna arranged in a plane perpendicular to the first axis of the crossbar so as to reduce coupling between the coils of the MD sensor and the antenna; wherein the transmit coil has an outer perimeter, the receive coil has an outer perimeter, and wherein at least a portion of the V-dipole antenna is within a cylinder formed by the projection of one of the outer perimeter of the receive coil or the transmit coil onto a plane perpendicular to a central axis of the V-dipole antenna.
