Claim One:
1. A method of locating the source of a signal, comprising: defining an area of interest as a discretized spatial region having a plurality of signal sources disposed in locations, the locations defined by a scan grid based on Cartesian positions; gathering, for each location in the area of interest, a set of sampled values indicative of a computed range to a signal source based on detection of a leading edge of a signal received from the signal source; rephasing the set of sampled values to generate a rephased set for accommodating a propagation delay in the sampled values, rephasing including applying an inverse of a propagation signal delay, the sampled values and the corresponding rephased values being identical to within a constant amplitude and phase factor of each other based on an accuracy of the computed range to the signal source; subdividing the rephased set of values associated with each location into a first region and a second region based on periodicity of a time domain of the gathered signals by, for each location, each of the first and second regions contains values indicative of either the leading edge signal or noise; determining if the first region is representative of the leading edge of a signal gathered from the signal source; computing, for each value in the rephased set, a metric based on comparing the first region and the second region, the metric indicative of a computed likelihood that the location contains the signal source; and rendering an indication of the location on the scan grid associated with the greatest computed likelihood of containing the signal source.
