摘　　要：提出一种将相位式空间目标定位机理应用到人工磁信标导航的方法。为提高人工磁信标导航的定位精度,引入相位式测角的思想。实验验证过程中,首先对单个永磁体和组合型永磁体的性能进行对比分析,得出组合体性能更好。然后通过仿真分析出磁力仪在不同方位、姿态情况下测得磁信号的相位信息与方位间的关系,说明了通过测量磁信号进行相位式空间目标定位机理的可行性。最后利用实验仪器进行实际测量,进一步验证了理论的有效性。A method of applying the phase-based space target positioning mechanism to artificial magnetic beacon navigation is proposed.In order to improve the positioning accuracy of artificial magnetic beacon navigation,the idea of phase angle measurement is introduced.During the experimental verification process,the performance of the single permanent magnet and the combined permanent magnet is firstly compared and analyzed,and it is concluded that the combined body has better performance.Then the relationship between the phase information and the azimuth of the magnetic signal measured by the magnetometer in different azimuths and attitudes is analyzed through simulation,which illustrates the feasibility of the phase-type space target positioning mechanism by measuring magnetic signals.Finally,the actual measurement is carried out with the experimental instrument,which further verifies the validity of the theory.
