摘要： 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.

摘要： A point-to-point, wireless, millimeter wave communications link between two stations at least one of which is a mobile station. A millimeter wave transmitter system operating at frequencies higher than 57 GHz with a tracking antenna producing a beam having a half-power beam width of about 2 degrees or less and a millimeter wave receiver also with a tracking antenna having a half-power beam width of about 2 degrees or less. In preferred embodiments each mobile station has a global position system (GPS) and a radio transmitter and both tracking antennas are pointed utilizing GPS information from the mobile station or stations. The GPS information preferably is transmitted via a low frequency, low data rate radio. Each millimeter wave unit is capable of transmitting and/or receiving, through the atmosphere, digital information to/from the other station at rates in excess of 155 million bits per second during normal weather conditions. In preferred embodiments actually built and tested by Applicants digital information has been transmitted at rates of 1.25 gigabits per second. Preferred communication links described here are millimeter wave links operating at frequencies of 71-73 GHz and 74-76 GHz mounted on simple two-axis gimbals. Pointing information of the required accuracy is provided by GPS receivers and standard radio links which send the GPS calculated positions to the millimeter wave systems at the opposite end of the link. In these embodiments there is no need for any complicated closed loop pointing information derived from received signal intensity or phase. On moving platforms locally generated inertial attitude information is combined with the GPS positions to control pointing of the gimbaled transceivers.

摘要： A high data rate free space communication link operating at millimeter wave frequency ranges. Links include two transceivers, the first transceiver transmitting at a first frequency range and receiving at a second frequency range and a second transceiver transmitting at the second frequency range and receiving at the first frequency range. Each of the two transceivers has a primary tunable oscillator providing a basic frequency signal that is precisely the same for both transceivers. Preferably the primary tunable oscillator in one of the transceivers, the slave oscillator, is slaved to the primary tunable oscillator, the master oscillator, in the other transceiver and the two transceivers are locked in frequency and phase. Also preferably the master oscillator is frequency controlled to maintain a constant number of wavelengths in the millimeter wave radio beams between the two transceivers, at least for periods of time permitting substantial data transmission without change in the number of wavelengths. In both transceivers a center frequency is generated by frequency multiplication and mixing of harmonics of the basic frequency signal generated by the transceiver's primary tunable oscillator. Preferred embodiments are designed to operate at frequencies above 60 GHz. In a particular preferred embodiment the center frequency for the first transceiver is about 73.5 GHz and the center frequency for the second transceiver is about 83.3 GHz. Embodiments of the present invention include automatic transmit power control, (preferably about 20 db of it, permitting operation at about 1 percent to 100 percent of maximum transmit power) for assuring adequate signal transmission in a wide variety of atmospheric conditions but not excessive power that might interfere with other links at the same frequencies. The narrow beam widths of these transceivers at about 0.5 degrees using a two-foot diameter antenna and the above transmit power control permit a large number of these transceivers to operate in the same region using the same frequencies.
