1. A computer-implemented method for identifying real and false emitters observed by an Electronic Measures System, wherein said real and false emitters are identified by pulse processing the received signals, de-interleaving the signals, emitter processing the signals determining emitter characterizing parameters for each apparent emitter, the method comprising the steps of: determining, using a processing unit, the variance of each emitter characterizing parameter; selecting, using the processing unit, those apparent emitters originating from the real emitter into a group; sorting, using the processing unit, the apparent emitters according to the variance of the emitter characterizing parameters; and identifying, using the processing unit, the apparent emitter with the least variance values as the real emitter, and the other apparent emitters in the group as false emitters.
