| 摘 要： | 随着弹道导弹系统技术的不断改进,影响导弹精度的工具类误差已逐渐降低,地球重力场扰动引力已经成为影响导弹命中精度的主要因素。这里从3个方面分析了扰动引力对弹道的影响,模拟结果表明,对于射程为10000 km以上的远程导弹,扰动引力的影响会造成超过1 km的落点偏差;5×10-5m s-2的扰动引力系统性偏差对导弹落点有明显影响。因此,扰动引力对导弹落点的影响不容忽视。

| Abstract: | With the improvement of ballistic missile system technology,the tool error affecting missile hitting accuracy has been reduced and disturbing gravitation has been a main factor.In this paper,the effect of the disturbing gravitation on ballistic trajectory was analyzed from three aspects.The simulated results showed that the impact point deviation caused by disturbing gravitation was more than 1 kilometer to long-range missile with the range exceeding 10 000 kilometers and the disturbing gravitation system deviation of 5 mGal had effect obviously on impact point.So,the effect of the disturbing gravitation on the impact point of trajectory was not allowed to neglect. |
