Handheld radar frequency scanner for concealed object detection
First Claim
1. A handheld radar frequency scanner system for detecting objects concealed on a person, the system comprising:
- a radar transmitter coupled to a transmit antenna that is configured and positioned to direct a radar signal at a person;
a radar receiver coupled to a receive antenna that is configured to detect a portion of the radar signal reflected by the person; and
a processor connected to the radar receiver and operable to process the portion of the radar signal detected by the radar receiver to determine whether the person is carrying a concealed object, by conducting a test in which a first characteristic of a first dielectric constant associated with the person is determined, and a second characteristic of a second dielectric constant associated with the concealed object is determined.

Abstract
A handheld radar frequency scanner system for detecting objects concealed on a person, the system includes a radar transmitter coupled to a transmit antenna that is configured and positioned to direct a radar signal at a person, a radar receiver coupled to a receive antenna that is configured to detect a portion of the radar signal reflected by the person, and a processor connected to the radar receiver and operable to process the portions of the radar signals detected by the radar receiver to determine whether the person is carrying a concealed object. The system may produce a real-time alert, such as an audible alert, when a concealed object is detected.

28. A method for detecting objects concealed on a person using a handheld radar frequency scanner system, the method comprising:
-
directing a radar signal at a person; detecting a portion of the radar signal reflected by the person; and processing the portion of the radar signal detected by the radar receiver to determine whether the person is carrying a concealed object, by conducting a test in which a first characteristic of a first dielectric constant associated with the person is determined, and a second characteristic of a second dielectric constant associated with the concealed object is determined. - View Dependent Claims (29, 30, 31, 32, 33)
