Switching Multiple Model Filter for Boost-Phase Missile Tracking
Henrique M. T. Menegaz, Simone Battistini · IEEE Transactions on Aerospace and Electronic Systems · 2018
This paper introduces a filter for tracking a ballistic missile during its boost phase. This filter includes a new switching algorithm and a modified interacting multiple model unscented filter (IMMUF), where the Markov transition matrix is time variable. Position, velocity, and all unknown parameters of a medium-range ballistic missile model are reconstructed. Simulations demonstrate that the new filter is able to consistently estimate a missile's trajectory and all unknown parameters and to outperform the previous forms of the IMMUF.
