(57) ABSTRACT
A method for detecting a concealed object in a target com
prising abody and the concealed object, the method including
emitting, by an emitter, radio frequency (RF) energy toward a
direction of the target, receiving, by a receiver, a scattered RF
energy reflected from the target, generating, by the receiver, a
signal corresponding to the received scattered RF energy,
comparing, by a processor, the signal with a plurality of
stored RF scattering signatures, each of the RF scattering
signatures being associated with an object of interest, and
detecting, by the processor, the concealed object when the
signal matches one of plurality of RF scattering signatures.
