Publication number: 20060017605Abstract: A millimeter wave portal imaging system for the detection of concealed weapons, explosives and other contraband items. A preferred millimeter wave imaging system includes a number (such as 64) of millimeter wave detection units each including a frequency scanning antenna and associated electronics. The units are mounted in four posts (16 per post) of a portal structure. Each unit collects frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view. The collected radiation from each unit is amplified at the collected frequencies and the amplified signals are separated into frequency dependent bins with a tapped-delay beam-former. These bins are then sampled to produce a one-dimensional image of the antenna field of view. A two dimensional image of a portion of a person passing through the portal is obtained by moving the person (or having the person move) across the field of view of each of the frequency scanning antennas.Type: ApplicationFiled: August 30, 2005Publication date: January 26, 2006Inventors: John Lovberg, Vladimir Kolinko, Robert Bible

Patent number: 6937182Abstract: A millimeter wave imaging system that includes at least one millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view. The collected radiation is amplified at the collected frequencies and the amplified signals are separated into frequency dependent bins with a tapped-delay beam-former. These bins are then sampled to produce a one-dimensional image of the antenna field of view. A two dimensional image of a target may be obtained by moving the target across the field of view of the scanning antenna. In a preferred embodiment the antenna is only 4.5 inches in length and constructed from WR-10 waveguide with inclined slots cut in one of the narrow walls at 79 mil spacings. This geometry creates a frequency-scanned antenna spanning a 20 degree vertical field of view over a 75.5-93.5 GHz operational band of the sensor, starting at approximately 1 degree below horizontal at 93.Type: GrantFiled: August 12, 2003Date of Patent: August 30, 2005Assignee: Trex Enterprises Corp.Inventors: John A.

Publication number: 20050116947Abstract: A passive millimeter wave imaging system that includes at least one millimeter wave frequency scanning antenna and multiple beam formers collecting narrow beams of millimeter wave radiation from a two-dimensional field of view. The collected radiation is amplified and separated into bins corresponding to various vertical and horizontal beam orientations. In a preferred embodiment the beam formers include one phase processor and 192 frequency processors. Two dimensional images of a target are obtained by the simultaneous detection of signal power within each beam and converting it into pixel intensity level at a rate of 30 frames per second.Type: ApplicationFiled: December 23, 2004Publication date: June 2, 2005Inventors: John Lovberg, Vladimir Kolinko, Richard Chedester

Publication number: 20050093733Abstract: A concealed weapons and contraband detection system combining metal detection equipment with millimeter wave imaging equipment. The preferred millimeter wave imaging equipment includes at least one millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view. The collected radiation is amplified at the collected frequencies and the amplified signals are separated into frequency dependent bins with a tapped-delay beam-former. These bins are then sampled to produce a one-dimensional image of the antenna field of view. A two dimensional image of a target may be obtained by moving the target across the field of view of the scanning antenna or by moving the antenna in order to scan its line of focus over the target. In preferred embodiments the millimeter wave imager is combined with an active eddy current type metal detector to provide a hybrid system providing important advantages over prior art security systems.Type: ApplicationFiled: July 30, 2004Publication date: May 5, 2005Inventors: John Lovberg, Vladimir Kolinko

Publication number: 20050003862Abstract: A wireless cellular communication system in which groups of cellular base stations communicate with a central office via a narrow-band millimeter wave trunk line. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same millimeter wave spectrum. In a preferred embodiment the trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A large number of base stations are each allocated a few MHz portion of a 900 MHz bandwidth of the millimeter wave trunk line. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth.Type: ApplicationFiled: March 12, 2004Publication date: January 6, 2005Inventors: Paul Johnson, John Lovberg, Kenneth Tang, Randall Olsen, Vladimir Kolinko

Patent number: 6587699Abstract: Equipment and methods for aligning the antennas of two transceivers of a point-to-point wireless millimeter wave communications link and keeping them aligned. Each of two communicating antennas is equipped with a telescopic camera connected to a processor programmed to recognize landscape images. The processors are programmed to remember the pattern of the landscape as it appears when the antennas are aligned. Each of the cameras then view the landscape periodically or continuously and if the landscape in view changes by more than a predetermined amount a signal is provided to indicate a misalignment. An operator can then take corrective action or alternatively the antenna system can be configured for remote or automatic realignment based of feedback from the camera.Type: GrantFiled: January 11, 2002Date of Patent: July 1, 2003Assignee: Trex Enterprises CorporationInventors: Randall B.

Patent number: 6556836Abstract: A point-to-point, wireless, millimeter wave communications link providing data transmission rates of over 1 billion bits per second (more than 1 Gbps) at ranges of several miles during normal weather conditions. In a preferred embodiment a communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. The transceivers are equipped with antennas providing divergence of less than 10−4 steradians so that an almost unlimited number of transceivers can use the same spectrum. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz. During very bad weather conditions this data link will not provide a 10−10 bit-error rate and 99.999% availability.Type: GrantFiled: May 2, 2001Date of Patent: April 29, 2003Assignee: Trex Enterprises CorporationInventors: John Lovberg, Kenneth Y.

Publication number: 20030022694Abstract: A wireless cellular communication system in which cellular base stations utilize multi-beam antenna to communicate with a large number of users. Each of the base station beams is a narrow beam of less than 10 degrees permitting reuse of available spectrum many times. A preferred antenna is described which broadcasts about 12 simultaneous beams, each about 5 degree, the 12 beams together covering a fan arc of about 60 degrees with the beams overlapping somewhat but interference is avoided by having adjacent beams broadcast at different frequencies within an authorized broadcast bandwidth. Six antennae mounted in a hexagonal manner thus cover a 360-degree azimuthal range. Preferably, users of the system communicate with the base station using a single narrow beam antenna directed at the base station.Type: ApplicationFiled: September 28, 2001Publication date: January 30, 2003Inventors: Randall Olsen, Chester Phillips, John Lovberg, Kenneth Y.
