    摘要: An apparatus determines the location of a signal source having coordinatesx,y). The source may be located as far away as two thousand km and does not require knowledge of ionospheric height or layer structure. The apparatus comprises at least three receivers adapted to receive the signals from the signal source. The coordinates, (x.sub.1,y.sub.1), (x.sub.2,y.sub.2) and (x.sub.3,y.sub.3), of each of the receivers are very precisely known. One receiver is capable of receiving signals from the other two receivers through different means (e.g. a wide-band telephone link). A plurality of at least three timers, one connected to each receiver, measures precisely the time difference of arrival (TDOA) of the signals from the signal source. A plurality of at least three means, connected one to each of the receiving means, determine the vertical angles .phi. at which the signal from the signal source is received by each of the receivers. More precisely, each receiver is in reality a phased array of individual antenna elements whose joint output can be used to measure both vertical angle and azimuth. Means are provided for calculating the coordinates (x,y) of the signal source from the measured vertical angles and the time differences of arrival.

    摘要: A beamforming apparatus is provided for processing the outputs of a linearrray of spaced apart receiving elements. The beamforming apparatus includes a surface acoustic wave device which has a pair of transducers mounted on a substrate in a spaced apart relationship. Each transducer is capable of receiving and converting an electrical chirp signal into an acoustic signal for propagation across the surface of the surface acoustical wave device. A plurality of taps are mounted on the substrate in a spaced apart relationship between the pair of transducers for receiving, sharing and converting the acoustic signals back into electric signals. Each tap is adapted to receive a bias voltage. A device is provided for mixing the signal from each tap with a signal from a respective receiving element so as to produce a plurality of mixed output signals, and another device is provided for summing the mixed output signals so as to provide a summed output signal. The summed output signal may then be processed by an upper sideband filter for controlling an indicating device. With this arrangement the beamforming is independent of the center frequency of the array from about 5 KHZ up to the millimeter frequency range.

    摘要: An apparatus is provided for processing the outputs of a two dimensional nar array of spaced apart receiving elements. The receiving elements are grouped and spaced apart in rows, which may be horizontal and vertical however, the rows may be in other directions provided they lie within a plane. The apparatus includes a plurality of surface acoustic wave (SAW) devices, each SAW device corresponding to a respective horizontal row of receiving elements and being capable of producing a plurality of horizontal phase shift outputs which linearly correspond to the number and horizontal spacing of receiving elements in a respective horizontal row. An additional SAW device is connected to the horizonatal SAW devices for introducing a vertical phase shift factor in the horizontal outputs of each horizontal SAW device so that each SAW device is capable of producing a plurality of combined phase shift outputs, the vertical phase shift factor corresponding linearly to the spacing of the receiving elements in a vertical direction. The apparatus further includes a mixer which corresponds to each horizontal SAW device for mixing the combined phase shift outputs with the respective outputs of the receiving elements in a respective horizontal row so as to produce a plurality of mixed output signals. If desired, the mixed output signals may be summed, processed by an upper sideband filter, and then fed to a video device. With proper controls of the horizontal and vertical scans of the video device two-dimensional imaging can be accomplished for indicating the direction and amplitude distribution of a radiating source with respect to the planar array of listening elements.With the present invention the beamforming is independent of the center frequency of the receiving element array from 5 KHZ up to the millimeter frequency range.

    摘要: Planar superconducting-normal-superconducting (SNS) Josephson microbridgesnd superconducting quantum interference devices (SQUIDs) with bridge widths of about 0.2 microns and lengths of about 0.1 micron or less are fabricated with the aid of a technique referred to as "shadow evaporation". The procedure permits the submicron dimensions to be set by edge film thickness and slant evaporation angle, both of which can be accurately measured. Microbridges have been constructed with vanadium banks or electrodes and gold-titanium bridges, although other materials can be used including superconducting metals for the bridge. It is expected that a refined version of this technique would be suitable for repeated batch fabrication of single and multiple Josephson microbridges.
