摘要： The present invention provides an improved antenna system that, in one embodiment, includes an antenna array comprised of a plurality of elements, each of which is capable of providing a signal. Also included in the improved antenna system is, a multi-beam beamformer for producing two spatially independent overlapping beams from the signals provided by two different subsets of the antenna array. The phase of the two beams is compared to realize an interferometer that can provide high or fine resolution data on the position of an object relative to the antenna system. The amplitude of the two beams can also be compared to obtain coarse data on the position of the object. The beamformer includes a switching network for selecting which elements of the antenna array form the two subsets. This permits, for example, the position of the beams to moved, the baseline of the two beams to be varied, and/or the beam width of the beams to be altered. To reduce adverse aerodynamic effects in certain applications, the antenna array is located conformal to the exterior surface of the body on which the array is mounted. Further, to reduce temperature related problems associated with high speed movement of the body on which the array is located, the array is located on the side of the body, as opposed to the front of the body. The side location also provides space for other types of sensors that are preferably located adjacent to the front surface of the body.

摘要： A beam-forming antenna system includes an array of integrated antenna circuits. Each integrated antenna circuit includes an oscillator coupled to an antenna. A network couples to the integrated antenna units to provide phasing information to the oscillators. A controller controls the phasing information provided by the network to the oscillators. In an alternative embodiment, the phasing to each antenna element is controlled through a fixed corporate feed network. The relative gains of the antenna signals received or transmitted through the fixed corporate feed may be adjusted with respect to each other to provide a beam steering capability.

摘要： An adaptive array antenna controller is disclosed that adaptively controls weighting coefficients of multiple antenna elements of an array antenna based on a digital signal outputted from an analog-to-digital converter receiving a weighted analog received signal from the array antenna. The controller includes an extractor for extracting a signal component for each sub-carrier contained in the analog received signal by Fourier transforming the digital signal. The controller adjusts the weighting coefficients so as to suppress a predetermined sub-carrier among plural sub-carriers.

摘要： The present invention provides apparatus and methods for determining a propagation time of a signal transmitted from a first location to a second location as a request signal and received as a response signal by the first location via a channel. In an example embodiment, a method comprises the step of determining the propagation time of the signal based on a local counter value that represents the time between transmission of the request signal and reception of the response signal, a remote counter value that depends on the request signal and being known to the first location, and a determinable time-delay value. The remote counter value represents an inter-time-delay between the reception of the request signal and the start of transmission of the response signal at the second location.

摘要： Antenna elements 101-1null101-2N, provided on a linear line at regular intervals to be parallel to each other, receive signals transmitted from the communicating partner, and output them to receiving beam former 103. In receiving beam former 103, phase shifters 104-1null104-N phase-shift the received signals input from the antenna elements of an even element number by null. Combiner 105 adds up the received signals that are phase-shifted by null in phase shifters 104-1null104-N and the signals input from the antenna elements of an odd number, and thus so forms a received beam. By this means, it is possible to realize an array antenna apparatus of a small and simple configuration that reduces the radiation of radio waves to the human body and equipment and that is influenced little by the human body and equipment.

摘要： A system for phase trimming of feeder cables, which are used for driving an antenna system uses a transmission pilot tone. A pilot tone device, which is arranged on the transmission side, produces the transmission pilot tone, which is input into each individual one of the feeder cables and is in each case passed, as a received pilot tone, to an output device which is connected upstream of the antenna system. Using the latter, the pilot tone is output from the respective feeder cable, and is processed further in order to determine phase differences between the feeder cables. The phase differences between the feeder cables determined in this way are compensated for by a trimming device, which is arranged between the input device and the feeder cables.

摘要： In an adaptive array antenna receiving apparatus, signal to interference ratio (SIR) measuring units are provided in signal processing units, respectively. The SIR measuring units measure signal to interference ratios of existing fingers to supply the measured results for an antenna weight succession processing unit. The antenna weight succession processing unit selects one of the existing fingers on the basis of the measured results. The antenna weight succession processing unit extracts antenna weights from one of the signal processing units that corresponds to the selected finger. The antenna weight succession processing unit supplies the extracted antenna weights to a newly assigned finger or one of the existing fingers that path timing is greatly changed.

摘要： A receiver is provided which can avoid demodulation performance from deteriorating due to changes in circuit constants caused by changes over time and temperature-dependent changes, prevent an increase in the receiver size, and realize a cost reduction. A switch control section is provided to perform control such that an input terminal of one of a plurality of phase varying circuits is selectively connected through a first switch circuit to any of an output terminal of an RF amplifier and a local signal output terminal of a local signal generating circuit, whereby the one phase varying circuit serves as a calibration circuit in the calibration processing that is executed in the non-reception mode. Also, the output terminal of the one phase varying circuit is selectively connected through a second switch circuit or a third switch circuit to any of one input terminal of a signal combiner and a first input terminal of a multi-port junction circuit in a multi-port direct conversion demodulating section.

摘要： A phased array antenna in space receives a beacon signal from an earth based beacon station at each of a plurality of antenna elements which make up the array. The beacon signal is passed to a beacon signal processor which determines the phase differences between the signal received at different antenna elements. The phase differences provide a measure of the physical displacement of the antenna elements from their nominal relative positions, due to distortion of the antenna structure resulting from, for example, gravitational forces. To correct for the effect of the displacement, phase compensation signals are generated corresponding to the phase differences and are applied to the communication signals being transmitted from and received at the antenna elements.
