Detection of concealed object on a body using radio frequency signatures on frequencies and polarizations

A method for detecting a concealed object in a target. The target may include a body and the concealed object. The method may include emitting radio frequency (RF) energy toward a direction of the target, receiving a scattered RF energy reflected from the target, generating a signal corresponding to...

Zusammenfassung:A method for detecting a concealed object in a target. The target may include a body and the concealed object. The method may include emitting radio frequency (RF) energy toward a direction of the target, receiving a scattered RF energy reflected from the target, generating a signal corresponding to the received scattered RF energy, comparing the signal with a plurality of stored RF scattering signatures, and detecting the concealed object when the signal matches one of a plurality of RF scattering signatures. Each of the RF scattering signatures may be associated with an object of interest.
