摘要： A system for estimating a location of a source transmitting a spectral-diversity signal having a known form but at least one unknown parameter is disclosed. The system comprises signal receiving circuits, each receiving the spectral-diversity signal and computing, for each signal carrier component in the spectral-diversity signal, a cross-ambiguity function based on the known form and on the received spectral-diversity signal. A central processor circuit estimates the location of the source, by calculating an extremum of an objective function constructed from all the cross-ambiguity functions.
