The invention provides a maneuvering target tracking method based on maximum correlation entropy extended Kalman filtering. The maneuvering target tracking method comprises the following steps: establishing a model set, a target state equation and a measurement equation of an interactive multi-model algorithm; the model probability, the target state vector, the covariance matrix and the Markov state transition matrix are initialized; carrying out input interaction between models, and linearizing a nonlinear model by using an extended Kalman filter; performing one-step prediction on each model, and designing a cost function based on a maximum entropy criterion; obtaining a posterior update value of the target in each model at the k + 1 moment through an iteration method; updating the model probability, correcting the transition probability, and finally fusing and outputting a tracking result. Through the above mode, the problem of nonlinear maneuvering target tracking under non-Gaussian ...
