The analysis of fall-point precision for impacting long-range strategic ballistic missile by space debris

Seeing that the space environment in which missiles flies has increasingly deteriorated, and the large threat has been worked by space debris, this paper builds a math model of the fall-point precision for impacting long-range strategic ballistic missile. By simulation and calculation, the influence of fall-point precision created by the impacting between missile and different sizes and different aspects space debris, and some conclusions can supply some references for warning of ballistic missiles' space fly.
