Abstract

Using numerical differentiation to describe kinematics of maneuvering target

the filtering model and combined filtering-predicting model are constructed to estimate kinematics parameters of tracked object

thus the present estimation or present-prediction estimation of position

velocity and acceleration can be obtained even though the dynamics of maneuvering target is unknown. Besides

the models constructed by this approach are rather simple

suitable estimate models for various applications can be created and it is easy to select appropriate estimate algorithm for satisfactory estimate quality

so that models based on numerical differentiation are robust estimate models. Simulation result shows good quality is obtained for tracking the object with violent dynamics by the estimate models proposed in this paper.
