Trajectory Reconstruction Using Paper Target Experiment Based on UKF

An effective method of trajectory reconstruction is presented in order to identify aerodynamic parameters. A novel smoother URTSS, which can get more optimal ballistic parameters, is introduced because of the biggish error caused by the uncertain initial conditions. Finally the validity of the method is verified by the experimental data. It also proves that URTSS can improves the accuracy of the identification of aerodynamic parameters.
