摘　　要：通过对弹箭参数影响弹道特性的规律进行分析,提出了一种利用非充分测量数据进行参数辨识校正弹道模型的弹道落点推算方法。计算结果表明,该方法可以实现对弹道长时间、长距离准确推算,对测试数据需求较小,随着测量数据长度的增加,推算结果趋于更加准确,方法具有通用性。Aiming at the problem that the reconnaissance radar cannot accurately estimate the trajectory under the condition of insufficient measurement data,the law of ballistic characteristics influenced by projectile parameters was analyzed.In this paper,a method of trajectory impact point estimation was proposed,which used incomplete measurement data for parameter identification and then corrected the trajectory model.The calculation results show that,this method can calculate the trajectory accurately in a long time and a long distance,and needs less test data.As the length of measured data increases,the calculation results tend to be more accurate,the method has a certain universality.
