基于中微子探测的测姿和定位方法研究

Attitude Measurement and Position Determination Based on Neutrino Detection

提出一种基于中微子探测的隐蔽环境载体运动状态确定方法.中微子是一种质量极小、仅参与弱相互作用的微观粒子,恒星发光、核反应堆发电等物理过程都会产生大量中微子.利用中微子传输信号的优势在于中微子具有极强的穿透能力,能够穿透行进路径上的天体.中微子信号源可作为导航信标,为隐蔽环境中的载体提供定姿和定位信息.分别设计了基于太阳等天然中微子信标的姿态确定方法和基于核电站等人造中微子信标的导航定位方法,上述方法的提出,有助于解决传统天文导航(CNS)和全球卫星导航系统(GNSS)在信号拒止环境中无法正常工作的问题.通过数学仿真验证了本文所提方法的有效性.

A dynamic state determination method for covered vehicle based on neutrino detection is proposed in this paper.Neutrinos are nearly massless,weakly interacting particles that come from a variety of sources including the sun,star and radioactive decay et al.Neutrinos are unique messages that can penetrate through the celestial bodies in their paths.Thus,the sources of neutrinos can be used as beacon to determine the attitudes and positions of covered vehicles.The attitude determination method and the position determination method based on the line-of-sight(LOS)measurements of neutrino sources are designed individually.These methods have the potential to solve the problem that the traditional celestial navigation system(CNS)and global navigation satellite system(GNSS)are not available in signal denial environment.The feasibility of the proposed method is verified via numerical simulations.
