Abstract:
A method of processing observed sensor array data to establish which among a plurality of hypotheses are true concerning said data, said data partitioned into sets of design data, each said set having a high probability of corresponding to one of said hypotheses, and test data that is to be tested for the truthfulness of each said hypothesis concerning said test data, said method comprising the steps of:(a) estimating the filter parameters for a plurality of differing multichannel hypothesis whitening filters from each corresponding said set of design data;(b) filtering said time sequence of signal vectors by said plurality of hypothesis whitening filters in parallel fashion to create a corresponding plurality of data residuals, each said multichannel hypothesis filter corresponding to a temporal model of said sensor array data for a particular said hypothesis;(c) selecting from among said data residuals the particular data residual which exhibits the greatest temporal and spatial whiteness, thereby declaring the corresponding hypothesis to be true concerning said test data.
