Anti-tank Missile Aerodynamic Parameter Identification

In this paper which was in the background of some model antitank missle, adopting maximum likelihood identification method estimated the aerodynamic parameters of the missle, with using flight datas.First, being based upon kalman filter, extended kalman filter formulas was established; second, with using extended kalman filter in non-linear dynamics system maximum likelihood identification method, the self-contained formulas of estimating parameter was established; third, according to the air layout of the missle, the aerodynamic parameters identification calculating model was gained, with applying to the non-linear dynamics system maximum likelihood identification method; finally, with using the calculating model, the aerodynamic parameters were gained. The results which were gained from the calulating model were almost consistent with which were gained from the wind tunnel experiment. Thus, it was viable to use the method to estimate the aerodynamic parameters.
