摘要： A method is disclosed to receive a signal, in a receiver from a transmitter (e.g., over a period of time). The signal propagates from the transmitter to the receiver in a direction of propagation. The receiver may move in a direction of motion relative to the transmitter. The signal includes a cyclic feature. The method may determine a change rate of a Doppler shift of the cyclic feature in the received signal. The method may determine, based on the change rate of the Doppler shift of the cyclic feature, an angle between the direction of motion of the receiver and the direction of propagation, the range between the receiver and the transmitter, and/or the locations of the transmitter and/or receiver.

摘要： Multiple radio transmissions are processed to determine, for each of a number of directions of arrival of the radio transmissions, a most direct direction of arrival, for example, to distinguish a direct path from a reflected path from the target. In some examples, the radio transmissions include multiple frequency components, and channel characteristics at different frequencies are compared to determine the direct path.

摘要： A Doppler Direction Finder comprises at least one antenna (52) spaced from a location point (53). The at least one antenna (52) is arranged in use to be rotated about the rotation point (53). The at least one antenna (52) is arranged to provide a first output signal comprising a signal received by said at least one antenna (52) combined with the Doppler Shift component. There are means (70) for providing a second output signal comprising the received signal without the Doppler Shift component. Processing means (54-82) process the first and second signals to obtain the Doppler Shift component. Determining means (88) determine from the Doppler Shift component the direction from which the received signal is received.

摘要： Directional characterization of a location of a target device makes use of multiple radio transmissions that are received from the target device. In some examples, each radio transmission is received at a first antenna at a fixed location, and is also received at a second moving antenna. The received transmissions are combined to determine the directional characterization, for example, as a distribution of power as a function of direction. In some examples, the received radio transmissions are processed to determine, for each of a plurality of directions of arrival of the radio transmissions, a most direct direction of arrival, for example, to distinguish a direct path from a reflected path from the target.

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： A dual mode device (110) comprising a communications block (120) and a satellite positioning block (130), each comprising respective Base Band (BB) blocks (123,132) and crystals or frequency sources (122,1312). The communications crystal (122) provides a cellular clock signal (FS1) to the satellite positioning block (130), which monitors the difference in the frequencies the crystals produce (FS1,FS2), using Vernier interpolation to gain a resolution greater than one clock cycle. The positioning crystal (1312) is used independent of the cellular crystal to demodulate satellite signals. The positioning BB (132) tracks the demodulated satellite signals compensating any errors caused by the positioning crystal signals (FS2) to the demodulation, using the information resulting from the monitoring. The communications crystal is capable to network based calibration and the positioning BB can compensate for the fluctuation thus caused in the cellular clock signal (FS1).
