基于波束指向对准的空空导弹短报文数据链技术研究

Research on Short Message Data Link of Air-to-air Missile Based on Beam Alignment

针对传统中远程空空导弹数据链传输距离有限的问题,首先提出了一种新的将短报文数据链应用于中远程空空导弹的全新作战方式,这种作战方式可以实现中远程空空导弹的超视距攻击能力和弹群协同作战能力,为第5代空空导弹网络化作战模式提供有力支撑。然后,为突破短报文数据链在弹上应用时波束方向相对固定导致通信成功率低的瓶颈,开展了波束指向对准技术研究,提出了滚转角控制和波束赋形联合对准方法,根据导弹位置将短报文天线方向矢量实时与卫星通信波束指向对准。最终,通过数字仿真,证明了采用该方法后可实现短报文在导弹飞行全程稳定通信,为短报文数据链应用提供技术支撑,具有工程应用价值。

The transmission distance of the traditional data link applied on the medium-long-range air-to-air missile is limited.Hence,a novel operational mode of the medium-long-range air-to-air missile which uses the short message data link is proposed in this paper.This mode can not only realize the over-the-horizon attack and multi-missile coordinated operations,but also support the network operations for the 5 th generation of air-to-air missiles.At the same time,there is the disadvantage of the low success rate when the short message data link is applied on the missile since the beam direction of the BD satellites is fixed.Therefore,the research on the beam alignment is carried out in this paper to solve the disadvantage.In this research,the joint alignment method with the rolling angle control and the beam-forming is proposed to align the antenna normal vector of short message and the beam direction of the BD satellites in real time based on the missile position.Finally,this beam alignment method is proved to be effective by the simulation experiment since it can build a reliable short message link in the whole process of the missile flight and provide technical support for short message data link,which has engineering application value.
