Abstract
A method for characterizing at least one signal source is disclosed. In one aspect, the method includes measuring, from a set of sensors, a set of technical data specific to the signals emitted by the signal source, grouping together the technical data in a set of classes depending on the correlations on the data and characterizing the signal source from technical data having been grouped together. The grouping step includes calculating correlations on the data n-tuples with n>2 and calculating a global partitioning error for different distributions of the data in classes. The global partitioning error is defined as a sum of the partitioning costs for all the n-tuples. The grouping further includes retaining as a grouping of data, the distribution in the classes minimizing the global partitioning error.
