An effective IMM algorithm for maneuvering target tracking

To reduce the complexity of algorithms for tracking maneuvering targets, a two stage filter scheme based on non-zero mean target dynamical model has been developed, and to maintain good tracking performance for non-maneuvering targets, an improved interacting multiple model (IMM) algorithm with the two stage filter has been suggested. The Monte Carlo simulation shows that this scheme posses a good tracking performance for both high maneuvering and non-maneuvering targets with substantially reduced computing burden.
