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

Abstract
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.

12. A method for detecting one or more concealed objects in a target comprising a body and the one or more 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, one or more signals corresponding to the received scattered RF energy; comparing, by a processor, each of the one or more signals 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 one or more concealed objects when the one or more signals match one or more of the plurality of RF scattering signatures.

13. A radar detector configured to detect a concealed object in a target comprising a body and the concealed object, the radar detector comprising:
-
an emitter configured to emit RF energy toward a direction of the target; a receiver configured to receive a scattered RF energy reflected from the target, and to generate a signal corresponding to the scattered RF energy reflected from the target; and a processor configured; to retrieve a plurality of stored RF scattering signatures from a stored data record; to compare the signal with the plurality of stored RF scattering signatures, each of the stored RF scattering signatures being associated with an object of interest; and to detect the concealed object when the signal matches one of plurality of stored RF scattering signatures. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
