Use of coherent signal dispersion for signal source association

A signal source association method and receiver. A receiver can be used to detect a plurality of signals transmitted from a plurality of transmission sources. The receiver can determine amplitude and phase information for a plurality of frequency components of each of the plurality of signals. The receiver can also determine a set of comparison values by comparing the respective amplitude and phase information from one or more pairs of the plurality of signals. Finally, the receiver can associate one of the signals with one of the plurality of transmission sources using the set of comparison values. The comparison values can comprise Stokes parameters and the one or more pairs of the plurality of signals can comprise a pair of orthogonally polarized signals or a pair of signals detected from spatially-separated antennas.
