    Abstract: The present invention is a multi-modal security checkpoint. The security checkpoint can simultaneously scan for and identify hidden metallic (weapon and shrapnel), non-metallic (explosives and IED), and radioactive/nuclear threats. The security checkpoint can also perform long range facial recognition and detect suspected terrorists. The security checkpoint combines many threat detection technologies into one checkpoint that allows it to be robust and detect a large variety of threats including hidden weapons, explosives, dirty bombs, and other threats.

    Abstract: Disclosed herein is a method and system for detecting potentially hazardous and/or explosive material concealed under clothing or in luggage. Through the emission, reflection, and reception of microwave radiation, a 3D image of a targeted area can be constructed. The image will show the outline of a moving person as well as any dielectric objects potentially hidden on their body. By measuring phases and amplitudes of microwaves reflected off a dielectric object, the optical path of the microwave through a hidden object can be determined, thus allowing for the creation of a 3D microwave image of a targeted area. Several emitters and receivers can be utilized at once, and video imaging can also be superimposed over the microwave image for improved detection accuracy. The invention has security and safety applications across the nation, particularly in areas of mass transit and large public events.

    Abstract: This invention addresses remote inspection of target in monitored space. A three dimensional (3D) microwave image of the space is obtained using at least two emitters. The data undergoes coherent processing to obtain maximum intensity of the objects in the area. This image is combined with a 3D video image obtained using two or more video cameras synchronized with the microwave emitters. The images are converted into digital format and transferred into one coordinate system. The distance l is determined between the microwave and the video image. If l lo then the presence of cavities is analyzed. If the cavity depth h is greater than the threshold value ho a concealed dielectric object at the target is ascertained: h 0 = l 0  ɛ - 1 √ ɛ where ε is dielectric permeability of the sought dielectric object.

    Abstract: Methods and systems for detection of threats in secure areas are disclosed. Microwaves are transmitted into high traffic areas and are reflected off or transmitted through targets within that area. The resulting signals are detected at receiving antennas which are designed to have a high cross-polarization discrimination (XPD) such that co- and cross-polarizations of the resulting signals are separable for further processing. The receiving antennas of the present invention comprise elliptical antennas with a double-ridged waveguide on the interior and a conically-shaped exterior. This particular design for the receiving antennas allows to technologically obtain an XPD of about 30 dB or more for solid angles measured from a receiving antenna's boresight (the main lobe axis), and formed by rotating the corresponding 30-degree planar angle around the main lobe axis, the solid angles measuring approximately 0.84 sr, in a frequency range between 9.5 and 20 GHz.

    Abstract: A method for standoff detection and analysis of objects comprises sending a signal through an inspection area, from a transmitter to a receiver, wherein the signal travels through objects in its path. If the signal encounters an object, through which it must travel, the speed of signal distribution decreases and its amplitude drops. A processor then determines the amplitude of the signal and whether the amplitude is above a given threshold, and if the threshold is met, further determining the shift in length of the signal's optical path, determining the thickness of the object, calculating the dielectric permittivity constant, and comparing this constant to known values of different materials to determine a preselected group of materials, to which the object in the inspection area belongs, and whether the inspected object belongs to a preselected group of dangerous objects. A system for detecting and analyzing such materials is also disclosed.

    Abstract: A barrier and system for the protection of a crowd from terrorists, by evaluating each individual for any concealed prohibited items. Each individual is exposed to one or more screening mechanisms, controlled by a monitoring unit, while passing in an organized fashion through an enclosed walkway containing the screening mechanism, and exiting on the other side. When a prohibited object is detected, response is provided and the smart door device is locked to detain and isolate the suspected individual in the device structure's interior. The structure of the invention is also configured to deflect the blast created by a potential explosion and prevent harm to other individuals and structures nearby.

    Abstract: The invention relates to the remote measurement of the dielectric permittivity of dielectrics. A 3D microwave and a 3D optical range images of an interrogated scene are recorded at the same time moment. The images are digitized and overlapped. A space between the microwave and optical image is measured, and a dielectric permittivity of the space between these images is determined. If the dielectric permittivity is about 3, then hidden explosive materials or components of thereof are suspected. The invention makes it possible to remotely determine the dielectric permittivity of a moving, irregularly-shaped dielectric objects.
