摘　　要：弹道导弹预警是能否成功拦截来袭导弹的决定性因素。分析了导弹预警卫星 (DSP)地面数据处理中心使用的传统数据处理方法在弹道导弹预警中的弊端 ,提出了运用三次参数样条函数计算预警弹道的新方法 ,研究了该方法的合理性、有效性以及优越性 。It is the early warning of the ballistic missile that plays a crucial role in the ballistic missile defense program at present. After analyzing the faultiness of the traditional data process method which used in the ground data record centre of Defense Support Program (DSP), a new method which deploying the cubic parameter spline function is brought forward in calculating the ballistic trajectory of the missile. The computation model of this method is presented in detail and testified by some samples. In the end, a conclusion is concluded that the new method has the advantage over the old one in veracity and validity.
