摘要
Building and maintaining a space object catalog requires rigorous methods for data association in order to maintain consistent object custody. There are three primary types of data association of interest in space surveillance: the observation-totrack association (OTTA) problem, the observation-to-observation association (OTOA) problem, and the track-to-track association (TTTA) problem. Recent work in the community has suggested the use of a number of information theoretic quantities as metrics for performing data association. This work presents a practical demonstration of using one of these quantities, the Bhattacharyya divergence, for TTTA in a small GEO catalog generation and maintenance exercise fed by data from a consortium of commercial electro-optical sensor providers. The Air Force Research Lab-developed Constrained Admissible Region-Multiple Hypothesis Filter (CAR-MHF) is used for primary orbit determination and track maintenance, including solving the OTTA and OTOA problems.
