摘要 精度性能和抗干扰性是陆基导航系统的两项重要技术指标,对导航过程影响很大。当陆基导航系统以弹道导弹为导航目标时,针对导弹的高动态特性,分析了影响导航精度的误差源及其量级,并基于主要误差源的作用机理提出了提高精度的技术途径。为了提高系统在复杂电磁作战环境下的适应性,提出了两项提高抗干扰能力的方案。最后对陆基导航站/SINS组合导航系统进行了仿真,结果表明陆基导航系统应用于组合导航能够有效地提高弹道导弹的射击精度。 Accuracy and anti-jamming capacity, as two important technical indexes of ground-based navigation system, affect the navigation process significantly. Aiming at the high dynamic performance of ballistic missile during navigation, the error sources which affect the accuracy and its order are analyzed, and the techniques to improve navigation accuracy are adopted according to the influence mechanism of errors. Two kinds of schemes to enhance the anti-jamming capacity of system are proposed in order to improve the adaptability in complicated electromagnetic environment. The ground-based navigation station/SINS integrated navigation system is simulated, and the results indicate that the application of ground-based navigation system could improve the fire accuracy of ballistic missile effectively.
