The wind has an important influence on the uncontrolled flight trajectories of projectiles. It is difficult to estimate the location of the conventional projectiles and correction projectiles if the wind speed variation in the flight range can not be obtained accurately. In order to improve the accuracy of trajectory prediction, a horizontal wind speed identification method using uncontrolled trajectory data and aerodynamic parameters is proposed. The law of dynamic equilibrium angle of projectile under wind condition is deduced, and then the relation equations between projectile accelerations and wind speeds are given. By sequential quadratic programming (SQP) method, the longitudinal and lateral horizontal wind speeds in different heights are estimated by using the acceleration data obtained by trajectory measurements. The simulation results show that the proposed method can estimate the horizontal wind speed in different heights and directions efficiently.
