摘要
计算了发射点位于全国范围内、经度纬度各相差5°、均匀分布的40个点的洲际弹道导弹被动段的扰动引力,分析了扰动引力对导弹落点的影响;绘制了落点偏差等值线图。结果表明:发射点位于我国西部地区时,扰动引力引起导弹被动段的落点偏差最大。通过分析扰动引力系统误差和随机误差对导弹被动段落点的影响,得出了扰动引力误差对导弹被动段落点的影响量级。
The passive phase disturbing gravity is calculated and the impacts on fall-point are also analyzed, on the assumption that intercontinental ballistic missile is respectively launched from 40 points, which equally located over our country with 5° differences on both latitude and longitude. The results indicated that the fallpoint deviation caused by disturbing gravity was maximal when the launch point was located in the west area of our country. Furthermore, the effects of the calculation errors of disturbing gravity on fall-point was analyzed and the affecting magnitude was given.
