摘要 从研究DSP预警卫星预警原理出发,分析了战术弹道导弹主动段的弹道特征和尾焰的红外辐射特性,从关机点速度预报偏差与射程偏差的角度,基于弹道学原理并利用三次样条插值方法,建立了DSP预警卫星对常规战术弹道预警能力仿真模型,通过仿真计算,可以发现在无干扰条件下,DSP预警卫星对弹道导弹落点预报精度非常高。 Based on researching the theory of the DSP early warning satellite, the characters of the initiative trajectory and the characters of the tail-flame' s infrared radiation of the TBM are analyzed. Using the theory of missile ballistics and spline function,a model to evaluate the early warning ability of the satellite is built,which aiming at the angle of forecasting error of closing engine point' s velocity and the range error. The simulation result shows that the forecasting precision of the satellite to the point of the missile is very high without interference.
