Claim:
1. A system for determining a real-world geographic location of an emission source emitting an electromagnetic energy signal, said system comprising: (a) a platform configured for movement; and (b) an apparatus disposed on said platform and configured to collect and process, in a passive manner and during movement of said platform, at least two pairs of successive samples of a weak electromagnetic energy signal emitted from the emission source and define, by extracting phase information from Fourier IQ data in said at least two pairs of successive samples of said weak electromagnetic energy signal through Fast Fourier Transform (FFT), angular and spatial coordinates of the emission source, one sample of said weak electromagnetic energy signal in each pair from said at least two pairs being processed, to extract said phase information, independently from but substantially simultaneously with another sample of said weak electromagnetic energy signal in said each pair from said at least two pairs.
