US Patent:

6831590, Dec 14, 2004

Filed:

Sep 12, 2002

Appl. No.:

10/241835

Inventors:

William Steinway - Smyrna GA
Gregory Stilwell - Orlando FL
Herbert Duvoisin, III - Orlando FL
David H. Fine - Lincoln MA

Assignee:

CyTerra Corporation - Waltham MA

International Classification:

G01S 1300

US Classification:

342 22, 342 27, 342 90, 342165, 342192

Abstract:

A concealed object detection system for detecting objects concealed on a person includes radar transponders that are each configured and positioned to direct a radar signal at a person and to detect a portion of the radar signal reflected by the person. A processor connected to the radar transponders processes the portions of the radar signals detected by the radar transponders 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.

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.

Appl. No.:

10/656808

Inventors:

William Steinway - Smyrna GA, US
Waymond Scott - Lilburn GA, US

Assignee:

L-3 Communications CyTerra Corporation - Orlando FL

International Classification:

G01S 13/88

US Classification:

342 22

Abstract:

A frequency-stepped radar may be used to detect buried landmines by sequentially inducing vibrations of different frequencies in the landmine. A sensor detects signals associated with the vibrations, and a processor processes the signals to detect the landmine.

Abstract:

Sensing characteristics of an object includes transmitting a stepped-frequency radar through an object and detecting, with multiple receiving structures, deflected portions of the radar signal. The detected portions are processed to generate processed data including information associated with amplitudes and phases of the deflected portions, and with the locations of the receiving structures at which the deflected portions were detected. The processed data is analyzed to determine information corresponding to dielectric properties particular positions within the object.

International Classification:

G01S 13/89
G01S 13/04

US Classification:

342 22, 342 28

Abstract:

Sensing moving entities includes transmitting a stepped-frequency radar signal including multiple frequencies through a wall from a first side of the wall to a second side of the wall. Portions of the radar signal that are reflected by entities located beyond the second side of the wall are detected. The reflected portions are processed to generate processed data including information associated with frequency shifts between the transmitted signal and the detected signal. The processed data is analyzed to determine if reflected portions are associated with moving entities.
