Network-centric angle only tracking using rank-deficient filtering
Nick Coult, J. Nate Knight · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
The coordinated use of multiple distributed sensors by network communication has the potential to substantially improve three-dimensional track state estimates even though each individual sensor might offer only low-dimensional measurements. For example, in the modern electronic warfare environment, hostile electronic countermeasures will endeavor to deny range and range rate information, leaving friendly sensors to depend on passive angle information for tracking. Other sensors may provide only range and bearing but not elevation. Herein we demonstrate algorithms for initiating and maintaining tracks in such operating environments with a focus on efficient representations of non-Gaussian density functions.
