Abstract:
A method of processing uncorrelated data from at least one multiple-contact tracking system, said method identifying which of a plurality of contacts being tracked the uncorrelated data is most likely to be associated with, said method comprising the steps of:providing reference data associated with reference contacts included in said plurality of contacts; comparing, in accordance with a first application of a bearing screen test, the uncorrelated data to said reference data associated with each of said reference contacts; comparing, in accordance with a first application of a total correlation test, the uncorrelated data to said reference data associated with first passing reference contacts to generate a comparison score between the uncorrelated data and each of said first passing reference contacts, the first passing reference contacts being a subset of the reference contacts passing said first application of said bearing screen test; comparing, in accordance with a second application of said bearing screen test, the uncorrelated data to reference data associated with one of said first passing reference contacts generating the greatest said comparison score during said first application of said total correlation test, wherein the uncorrelated data is combined with said reference data associated with said one of said first passing reference contacts generating the greatest said comparison score to define an updated reference contact when said second application of said bearing screen test is passed, and wherein the uncorrelated data defines a new reference contact when said second application of said bearing screen test is failed; comparing, in accordance with a third application of said bearing screen test, one of said updated reference contact and said new reference contact to said reference contacts; and comparing, in accordance with a second application of said total correlation test, said one of said updated reference contact and said new reference contact to second passing reference contacts to generate a comparison score between said one of said updated reference contact and said new reference contact and said second passing reference contacts, said second passing reference contacts being a subset of said reference contacts passing said third application of said bearing screen test, wherein the uncorrelated data defining said one of said updated reference contact and said new reference contact is combined with said reference data associated with one of said third passing reference contacts having the greatest said comparison score generated by said second application of said total correlation test when the greatest said comparison score generated by said second application of said total correlation test exceeds a threshold value.
