摘要： A spatial location system capable of spatially locating a device in three dimensions is described comprising at least three of: a transmitter and a receiver, together with an antenna array operably connected to each, wherein each antenna array is capable of varying a pointing angle of at least one antenna lobe independently without the need to move either the antenna array or its constituent parts physically and wherein at least three antenna lobes are arranged such that they may partially intersect at one or more pointing angles under electronic control. The antenna array may, for example, comprise at least a first sub-array and at least a second sub-array wherein the second sub-array is oriented substantially orthogonally to the first sub-array and at least a third sub-array wherein third sub-array is positioned at a location which is not coincident with the location at which the at least a first sub-array is positioned. The pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of a first sub-array and the pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of at least a second sub-array together with the pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of at least a third sub-array may be independently controllable in order to allow each to separately locate a signal which falls within their respective steering ranges. A point within the area of intersection of the three or more beams, when they are arranged to point at a signal to be located, may be reported to a further process or system as a three-dimensional spatial location of the signal source or its transmitting antenna.

摘要： An antenna apparatus is provided for use as a base station in a wireless network, and additionally a method is provided for performing spatial nulling within such an antenna apparatus. The antenna apparatus has an antenna assembly that employs a reception beam pattern selected from a plurality of reception beam patterns. During a nulling test operation, a reception beam pattern controller is arranged to cause the antenna assembly to employ each of the plurality of reception beam patterns. Quality metric determination circuitry then determines, for each reception beam pattern employed during the nulling test operation, a link quality metric for each of a plurality of wireless terminals, based on communication between those wireless terminals and the base station whilst the antenna assembly is employing that reception beam pattern. Reception beam determination circuitry is then arranged to determine, from the various link quality metrics, a reception beam pattern from amongst the plurality of reception beam patterns that is to be used for a subsequent communication with the plurality of wireless terminals. By such an approach, it is possible to alter a reception beam pattern so as to seek to reduce the effects of an interference source whilst also seeking to maintain an appropriate level of link quality in respect of each of the various wireless terminals that are communicating with the base station.

摘要： A system for directionally classifying of a radio signal originating from an emitter. The system includes a receiving-station, which includes at least two antennas, a single-channel-receiver producing a first and a second received signals and a switch alternately coupling each of the antennas with the single-channel-receiver. The system further includes another receiving-station which includes another receiver, producing another received signal, coupled with a first other antenna. The system further includes directional-classifier which includes a phase-difference-detector, coupled with the single-channel-receiver and with said another receiver. The phase-difference-detector produces a first phase difference measurement when the switch couples one antenna with the single-channel-receiver. The phase-difference-detector further produces a second phase-difference-measurement when the switch couples the other antenna with the single-channel-receiver. The directional classifier subtracts the second phase-difference-measurement from the first-phase-difference measurement producing a phase-difference-estimate. The receiving station and the other receiving station are in relative motion one with respect to the other.

摘要： The delay between two signals is determined by: splitting each signal into quadrature components; obtaining zero crossings from a component of one signal, and using each crossing to trigger the sampling of the components of the other signal, repeating the sampling while introducing different time shifts between the signals to obtain a pair of representations of the sampled components, and using zero crossings of one representation to sample the other representation. The result is a sample pattern having a position, relative to the introduced time shift, determined by the delay between the signals.

摘要： In a geolocation application, a method is provided to jointly estimate the time-of-arrival (TOA) and the amplitude of a received signal based on super-resolution technique. The super-resolution joint TOA-amplitude estimators are provided based on either the expectation-maximization (EM), parallel-interference-cancellation space-alternating generalized expectation maximization (PIC-SAGE) or serial-interference-cancellation SAGE (SIC-SAGE). The SIC-SAGE estimator minimizes the ranging estimation error especially under a non-line-of-sight (NLOS) condition. The SIC-SAGE estimator is a simplified version of the maximum likelihood estimator with more stable performance in a multipath rich environment, such as the ultra-wideband (UWB) based applications. These techniques provide the following benefits: 1) it is generic, so that signal processing can be deployed on both time-domain (e.g., UWB impulse-radio) and frequency-domain (e.g., multi-band orthogonal frequency-division multiplexing (MB-OFDM)) based transceiver schemes and applicable for both UWB and non-UWB systems; 2) it is robust especially under NLOS condition and multipath rich environment.

摘要： An implanted fluid access port locator system for adjustable gastric bands. The system may include an access port having an RFID tag with its antenna adjacent to the receiving portion of the port. An external locator with radio frequency transmitter/receiver circuitry sends read or interrogation signals to the RFID tag and may send write signals to the tag to write treatment data to memory of the RFID tag. The locator may include an antenna array with four patch antenna arranged in pairs to model two monopulse radar antenna systems. The locator also includes processor(s) and logic modules/circuitry for processing the tag response signals received by the antenna array to determine location information for the RFID tag and associated port, i.e., to identify the center of the port relative to the antennae array or array face such as with strength and direction information relative to the array face. A method of locating implanted fluid access port includes providing radio frequency transmitter/receiver circuitry on the access port and manipulating a handheld locator outside the body to pinpoint the position and orientation of the access port. A mark may be made with a handheld locator to direct insertion of a needle for adding or removing fluid from an implanted system through the access port.
