摘要 研究了影响弹道导弹落点预测精度的主要因素,分析了探测设备误差、地球引力势能中第2阶带谐波的截断误差、未考虑地球稀薄大气层的误差和再入段大气风等因素对落点预测精度的 影响,利用外弹道修正理论提出了一种解析的落点预测精度评估方法.算例分析表明,该评估方法 有效. The main factors influencing the precision of ballistic missile impact-point prediction are studied.The influences to the impact-point prediction precision are analyzed,including the measuring device error,the 2nd order band harmonic truncation error in the earth gravitational potential energy,error caused without considering the thin atmosphere and the atmosphere breeze in missile reentry phase,etc..An analytic precision evaluation method for the impact-point prediction based on exterior ballistic correction theory is proposed.The calculating analysis shows that the evaluation method is effective.
