摘　　要：针对基于涡轮发电机输出频率的弹道辨识方法在非标准气象条件应用不能保证辨识精度的问题,提出了用于修正风对该弹道辨识方法辨识精度影响的算法。该算法通过事先建立多个特定风速下涡轮发电机输出信息对应的速度与所辨识弹道参量的拟合关系,再利用实际风速与对应特定风速关系进行插值来修正辨识结果。仿真结果表明:该修正算法能够有效消除风对原弹道辨识方法辨识精度带来的不利影响,增强了弹道辨识方法的环境适应性。n order to eliminate wind’s negative effect on mortar bomb’s traj ectory discrimination precision,a correction algorithm was put forward.Firstly,this correction algorithm established the polynomials of velocities calculated through turbine alternator output frequency to traj ectory parameters,secondly,above-mentioned pol-ynomials and the relation of real wind velocity to some given wind velocities were used to correct the discrimina-tion results gained through mortar bomb’s traj ectory discrimination method put forward by author.Simulation results indicated that this correcting algorithm could eliminate negative effect caused by wind efficiently and en-hanced the adaptability of mortar bomb’s traj ectory discrimination method to circumstance.
