弹道导弹再入段大气参数修正

Atmosphere Parameter Error Correction on Range of Reentry Ballistic Missile

为了提高弹头落点精度,在分析大气参数偏差对弹头再入精度的影响和实际大气参数与标准大气参数差异的基础上,运用实测大气参数,拟合建立了再入大气参数的修正模型,并分析了模型的可靠性。通过弹道仿真计算表明,建立的修正模型有效地提高了弹头再入落点精度,该修正模型是切实可行的。

In order to improve the inpact accuracy of reentry warhead, on the base of analyzing the affection of atmospheric parameters that used in ballistic calculation, the importance of the atmospheric parameters was introduced. Based on actual analysis atmospheric parameter, an atmospheric parameter error correction model was build. The ballistic simulation calculation shows, the correction model effectively improve accuracy of the reentry warhead, and the model is correct.
