DETECTION OF CONCEALED OBJECT ON A BODY USING RADIO FREQUENCY SIGNATURES ON FREQUENCIES AND POLARIZATIONS

摘要

A method for detecting a concealed object in a target comprising a body 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.

1. A method for detecting a concealed object in a target comprising a body and the concealed object, the method comprising:
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 stored RF scattering signatures.
