摘要
攻击大机动目标的导引律是高性能防空反导导弹的关键技术之一。比例导引法由于其形式简单、制导系统技术上易于实现,已得到广泛应用。以某型反导导弹为例,针对目标做大机动运动时比例导引存在捕获区域变得有限的问题,提出了比例导引的两种扩展算法:引入目标加速度补偿的比例导引和引入视线加速度补偿的比例导引,并进行了数值仿真分析。结果表明,采用这两种扩展比例导引律,攻击大机动目标时制导精度高,对导弹的过载要求小,脱靶量小,弹道较为平直。
One of the key techniques of high performance aerial-defense antimissile missile is the design of the guidance law for large maneuvering target. Proportional navigation(PN) guidance is the most widely used law,which is simple and easy to implement on the technology of guidance system. Two generalized algorithms of PN laws with target acceleration compensation and angular acceleration of line-ofsight compensation are presented by taking anti-tactical ballistic missile for example for the limited capture domain of proportion navigation guidance law in capturing the large maneuvering targets. And the results of numerical simulation are analyzed. The results show that the two generalized guidance laws have high accuracy against the maneuvering targets,the required overload of the missile and the miss-distance are small,and the ballistic trajectory are relatively smooth.
