Aiming at the problem of model complexity during the process of target tracking,a new uniform accel-eration circular motion model,which can describe many types of motional models,is put forward. Firstly,the relationship between the state vectors of uniform circle motion model is given. Then,by analysing the features of uniform acceleration circular motion model,a velocity model of target is established in cartesian coordinate. By using the theorem of calculus,the mathematical derivation of position and acceleration model is given. Finally, the validity of the motion model is verified by mathematic proof and simulation results.
