Abstract
A system for the electronic detection of military threats includes an electromagnetic (EM) gradiometer for detecting secondary EM waves scattered from objects illuminated by a primary EM wave existent in a local area. A right magnetic dipole antenna and a left magnetic dipole antenna are included in the EM gradiometer for receiving the secondary EM waves and able to reject the primary EM wave. A synchronizer derives a reference signal to the EM gradiometer from the primary EM wave. A synchronous detection processor makes measurements of the phase and amplitude of the secondary EM waves. A graphical user interface (GUI) is used to display information about the location of objects assessed to be threats in the local area that were computed from the measurements of the phase and amplitude. A vehicle may be used to transport the EM gradiometer over the local area during periods the objects are being radio illuminated.
