摘要： 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. Antennas are described to maintain beam directional stability to less than one-half the half-power beam width. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz and the half power beam width is about 0.36 degrees or less. Thus, in this system the low frequency band width is efficiently utilized over and over again by dividing a territory into small cells and using low power antenna. And a higher frequency bandwidth is efficiently utilized over and over again by using transmitting antennae that are designed to produce very narrow beams directed at receiving antennae. In a preferred embodiment cellular base stations are prepackaged for easy quick installation at convenient locations such as the tops of commercial buildings.

摘要： A short range millimeter wave surface imaging radar system. The system includes electronics adapted to produce millimeter wave radiation scanned over a frequency range of a few gigahertz. The scanned millimeter wave radiation is broadcast through a frequency scanned transmit antenna to produce a narrow transmit beam in a first scanned direction (such as the vertical direction) corresponding to the scanned millimeter wave frequencies. The transmit antenna is scanned to transmit beam in a second direction perpendicular to the first scanned direction (such as the horizontal or the azimuthal direction) so as to define a two-dimensional field of view. Reflected millimeter wave radiation is collected in a receive frequency scanned antenna co-located (or approximately co-located) with the transmit antenna and adapted to produce a narrow receive beam approximately co-directed in the same directions as the transmitted beam in approximately the same field of view. Computer processor equipment compares the intensity of the receive millimeter radar signals for a pre-determined set of ranges and known directions of the transmit and receive beams as a function of time to produce a radar image of at least a desired portion of the field of view. In preferred embodiment the invention is mounted on a truck and adapted as a FOD finder system to detect and locate FOD on airport surfaces.

摘要： A broad-band millimeter wave imaging system with improved thermal resolution as compared to prior art devices. The system is useful for producing images of metal and non-metal objects such as guns, knives and explosives hidden under clothing. A cylindrical antenna focuses millimeter wave radiation from a substantially one dimensional section of a target region onto a linear array of radiation collectors. Radiation collected at each collector is amplified to produce a set of amplified millimeter wave signals and the amplified signals pass through focusing delay lines to a millimeter wave lens. Millimeter wave signals are collected at the output of the lens and the collected signals are monitored by an array of detectors. The combined effects of the delay lines and the lens produce a focus of the amplified millimeter wave radiation emitted and reflected from the one dimensional section of the target region. The array of millimeter wave detectors at the focus of the lens produces a one dimensional image of the one dimensional section of the target region. The antenna is scanned to produce a two dimensional image of the complete target region. The two dimensional image is displayed on a monitor screen. A full two-dimensional image of a human subject located at a stand-off distance of several meters (e.g., 7 meters) from the imager is acquired in few seconds time frame.

摘要： 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. The images from the antennas can be monitored separately or data from the antennas can be combined with a computer processor to form images of the person.

摘要： A frequency-modulated continuous wave (FMCW) millimeter-wave (MMW) radar system. Preferred embodiments operate within a frequency range between about 77 and 81 GHz (wavelengths between about 3.846 mm and 3.304 mm). The MMW frequency in these embodiments is increased or decreased (“chirped ”) in a very linear fashion over some or all of this operating frequency range. Over the chirp period, the time derivative of the transmit frequency, df/dt, is held constant. In the time τ it takes for the radar's transmit signal, moving at the speed of light c, to travel from the antenna to a target at a range R and return back to the antenna (τ=2R/c), the transmitter's output frequency will have moved by an amount (df/dt)*τ. Thus, the more distant the reflecting target, the greater the two-way signal time of flight and consequently the greater the frequency change. By mixing the delayed returning signal with the current transmitter output signal, this difference frequency is measured directly, determining uniquely the distance from the radar to the reflecting target.
