Abstract:

This paper presents some recent results involving track level fusion in a distributed tracking environment. Successful fusion for the application requires that target state estimates and their error covariance matrices be available for processing. For this study, the limitations associated with several of the existing communication links missing covariance and how we can recover track covariance matrices from track quality parameters, are being dealt with. An algorithm for reconstructing an error covariance from on offboard track system is presented using the notion of an ambiguous measurement set. The performance of this approach is demonstrated in several simulated test cases.
