导弹防御系统目标速度计算方法研究

针对两点法计算高动态物体运动速度时误差较大的问题,在分析弹道导弹运动特性的基础上,提出了等时间间隔、不等时间间隔和带补偿的三种速度计算方法.仿真算例表明,这三种计算方法的计算精度远远高于传统的两点速度计算方法,其中带补偿的速度计算方法具有适用范围广、精度高的特点,可用于雷达探测弹道导弹运动速度的计算.

On the Computational Method for the Object Velocity of a Missile's Defense System

Great error will occur inevitably when the traditional two-point method is used to compute the velocity of high dynamic objects.Based on the analysis of ballistic missile's kinematic properties,three computational methods for velocity are proposed to overcome the shortcoming of the two-point method,and they are the equivalent time interval method,nonequivalent time interval method,and the method with compensation respectively.Simulation shows that the computational accuracies of the proposed methods are higher than that of the traditional two-point method,moreover,the method with compensation has the properties of wide application and high accuracy,which is enable to be used to compute the ballistic missile's velocity detected by radar.
