Abstract
The location of a transmitter transmitting a signal may be estimated by receiving the signal at each receiver of a plurality of receivers, where the receivers are in motion relative to the transmitter. The following are performed for pairs of receivers to yield phase differences: establishing a first phase offset of the signal as received at a first receiver; establishing a second phase offset of the signal as received at a second receiver; and determining a phase difference corresponding to the pair of receivers in accordance with the first phase offset and the second phase offset. A location of the transmitter is estimated in accordance with the plurality of phase differences.
