Interacting Multiple Model Filtering Algorithm Applying in Surveillance Radar

A new Interacting Multiple Model(IMM) filtering algorithm is applied in surveillance radar in this algorithm.Constant velocity model interactering with constant acceleration model,constant velocity model interactering with Singer model,constant velocity model interactering with"Current"statistical model and Singer model interactering with"Current"statistical model are used for target tracking.Through a mass of computer emulatoring,how to advance filtering precusion most for different aviation contrail is discussed.And the filtering capability of IMM is compared with filtering capability of Kalman filtering which has been applied in engineering.
