遥测数据重建弹道校正方法

Research on the Correction of Trajectory Reconstruction Based on Telemetry Data

弹道导弹遥测系统数据丢帧一般采用直接插值法进行校正,这对导弹运动速度和位置而言精度不高。文中在分析弹道导弹运动特性的基础上,提出视速度增量校正方法,仿真表明该方法的计算精度高于直接插值计算方法。在此基础上利用该方法对速度和位置数据进行了增密,得到了步长小、精度高的增密数据。

The current correction of the lost frame telemetry data is direct interpolation.The accuracy is not good enough for the data of velocity and position.The Method of acceleration correction is proposed based on the analysis of the movement characteristics of ballistic missile.The simulation show that this method is better than the former.The data step length of velocity and position are improved by this way.
