Abstract :
We explore criteria for filter consistency and develop methods of determining target track lifetimes without truth information. Two statistical tests, a sliding window likelihood function and a quadratic ratio of the Wishart matrix, are applied to a distributed fusion architecture. Simulation studies are used to compare the performance of these tests against a measure of track lifetime based on using the true states
