<p>The present invention relates to a radio frequency emitter detection and location method where a number N, the number N being at least three, of receiving units (28, 29, 30, 31 ), using the same bandwidth B, centre frequency f<SUB>c</SUB> and measurement time duration T, are used (36) for receiving signals S<SUB>0</SUB>, S<SUB>1</SUB> ... S<SUB>N-1</SUB> from at least one emitter (27), the method comprising the steps: calculating (37) a correlation function c between the received signals s<SUB>0</SUB>, s<SUB>1</SUB> ... S<SUB>N-1</SUB> , using one of the received signals S0 as a reference, where HOS (Higher Order Statistics) is used for performing said calculation of the correlation c; and using (38) said correlation function results to form volumes of probabilities in a subset of an N-1 -dimensional space of information regarding the location of a certain emitter (27), where each correlation function result in said subset corresponds to a single point in the physical space. The present invention also relates to a corresponding system.</p> |
