Abstract–An adaptive Interacting Multiple-Model (IMM) estimator using a small number of models is proposed for maneuvering aircraft tracking. It estimates the difference between the true target control parameter and the value currently used in the IMM models to improve the estimator’s performance. The algorithm performance is compared with the performance of a standard IMM estimator for some maneuver scenarios via Monte Carlo simulations.
