Abstract
Firstly we analyse the properties of Strong Tracking Filter (STF) and Interacting Multiple Model(IMM) algorithm and find that STF is a parameter-adaptive algorithm and IMM is a model-adaptive algorithm. It means that they may be combined effectively. Secondly we propose a new method based on the Least-Squared Estimation to search for the fading factor in STF. After that, we design a Strong-Tracking Multiple Model Estimator (STMME) by combining the new STF with IMM. Finally, the simulation show that STMME greatly improves accuracy of velocity and acceleration compared with the conventional IMM when tracking the maneuvering target. And the computation burden increase only 6%.
