基于虚拟导引的空空导弹程控弹道设计技术

Design Method of Program Trajectory Based on Virtual Guidance for Air-to-Air Missile

针对采用弹道成型技术的空空导弹,在程控弹研制阶段验证导弹射程的程控弹道设计,常规的弹道设计方法不能满足实际需要,提出了引入虚拟目标结合扩展比例导引律,实现自动形成控制指令的虚拟导引程控弹道设计,极大地减少了弹道指令拟合的繁琐工作,而且能够准确实现试验目的;该方法在实际工程应用中也得到了验证,在空空导弹研制过程中,具有很强的普适性,可在工程研制过程中广泛使用。

In the development of air-to-air missile adopting the shaping-trajectory technology, the conven- tional program trajectory design method cannot fulfill the material need to validate the maximal range of missile. This paper proposed a method to employ the expansive proportional guidance law with virtual tar- get and to design program trajectory with the automatic formation of virtual guidance program instruction. And the fussy job to approach the trajectory program instruction was reduced significantly, further more this design may implement the test intention. This method is validated in the factual engineering application ex- ample and may be used widely in the development of air-to-air missile by reason of strong and all-pervading applicability.
