Gating techniques for maneuvering target tracking in clutter
Wang X., Challa S., Evans R.
Gating techniques for maneuvering target tracking using an IMM-PDA filter are considered in this paper. Existing gating techniques, namely, Centralized Gating and Model Based Gating are reviewed and new gating techniques, called Model Probability Weighted Gating and Two-Stage Model Probability Weighted Gating, are proposed. A benchmark trajectory and a random scenario are considered for performance evaluation of the gating techniques in terms of RMS errors, percentage of track loss and computational load.
