Abstract: An antenna system includes a first metal housing portion having a metal housing connecting edge, the first metal housing portion having a triangular side profile, and a second non-metal housing portion having a non-metal housing connecting edge, the non-metal housing connecting edge being complimentary to the metal housing connecting edge of the first metal housing, the second non-metal housing portion having a triangular side profile. A first and second dipole antenna are printed on a circuit board positioned in the non-metal housing portion. The first and second dipole antennas are configured such that the direction of the first and second dipole currents are approximately normal to a plane defined by the metal housing connecting edge.

Abstract: An array of paired V-band sensors is provided to act as a virtual fence to detect human intrusion. Each sensor includes a rotating circuit board that includes an antenna array. The sensor pivots the circuit board with regard to a weight base to align with an opposing sensor. By alternatively transmitting and receiving with regard to the opposing sensor, a V-band bistatic radar system is enabled that detects human intrusion between the opposing sensors.

Abstract: A plurality of power amplifiers are integrated into a semiconductor substrate and coupled to a corresponding first plurality of antennas on an adjacent first microwave substrate. A second microwave substrate carries a second plurality of antennas coupled to a combining network. The second microwave substrate is separated from the first microwave substrate to allow a free space combination of RF energy propagated by the first plurality of antennas.

Abstract: A system includes a multi-system approach to detecting concealed weapons and person borne improvised explosive devices (PBIED). A first and second radar system operate at different center frequencies to provide, respectively, isolation of a target of interest from clutter and fine detail information on the target, such as whether the target is a living person, whether a concealed object may be present, material composition of the object, and shape, size, and position of the target relative to the system. Circular polarized radar beam may be used to distinguish a suspect object from within a crowd of people. Radar image of the object may be overlaid on visual image of a person carrying the object. Radar tracking of the object is coordinated with visual tracking of the target provided by a camera system, with visual display and tracking of the target overlaid with the radar information.

Abstract: A system includes a plurality of radar units configured to provide scan data to a network; a signal processing and imaging module connected to the network and configured to receive the scan data, identify a target, and determine a type of the target based on a radar profile of the target; and a display unit in communication with the signal processing and imaging module and configured to provide a tracking display of the target position and type. A method includes scanning an inhabitable area using a plurality of radar detector units to produce scan data; processing the scan data to construct a digitized representation of a target in the inhabitable area; using recovered information of the target to differentiate between a live person, an animal or an object as the target type; and displaying the target type and position on an image display.

Abstract: Systems and methods include up-converting a UWB frequency pulse from a UWB radar unit to a V band frequency pulse; transmitting the V band frequency pulse via an active array antenna; receiving a V band echo pulse via the active array antenna; down-converting the V band echo pulse from the active array antenna to a UWB pulse; and feeding the UWB pulse to the UWB radar unit for processing by the UWB radar unit. A V band antenna system includes: an antenna board that defines an antenna plane being the plane of the board and comprising a plurality of antenna elements; a mother board providing a corporate combining feed to the antenna board; and a power management board to which the antenna board and mother board are mounted perpendicularly to the antenna plane, wherein the antenna elements provide a beam forming antenna for ultra wide band pulses at V band frequencies.
