A new IMM algorithm using fixed coefficients filters (fastIMM)

In this paper we present an new approach based on two filters αβαβ and αβγαβγ using Interacting Multiples Models (IMM) design instead of a Kalman filter second and third order for the tracking a single maneuver target. The comparison between the proposed filter and the IMM improves the computing time amount about 60% while having a high accuracy.
