Abstract : A method of processing uncorrelated data from at least one multiple contact tracking system is provided. The method identifies which of a plurality of contacts being tracked that the uncorrelated data is most likely to be associated with. By combining correlation with reassessment processing, correlation errors can be reduced or minimized. A threshold test (e.g., bearing test) is used to screen or coarsely filter the data while a comparison scoring test is used associate the uncorrelated data with one of the contacts. The same threshold test and comparison scoring test are used for both correlation and reassessment processing.
