摘要
文中针对卫星拒止环境下,海上无人多域移动平台及其编队,对导航定位功能最低保障的迫切需求,开展了一系列研究。首先,分析了直线阵测角的方法,分析了不同波长、阵元间距、噪声下的测角情况,并采用谱估计对多信号同时测角情况进行了仿真;其次,对圆阵构型测角进行了分析,分析了不同参数下的测角情况,并对多信号同时测角进行了仿真;最后,文中提出了海上无人集群自构建海域圆阵、线阵、正交阵复合协同定位的方法,阐述了海上无人跨域应用的基本思想。相关的分析、图表、数据证明了文章的新颖性和潜在的实用价值,其思想对相关技术的发展和探索具有较强的拉动作用。
In this paper,a series of studies are carried out to meet the Urgent requirements of unmanned multi-domain mobile platforms and their formations for the minimum guarantee of navigation and positioning functions in GNSS Denial Environment.Firstly,the Angle measuring method of linear array is analyzed,and the Angle measuring conditions under different wavelength,array spacing and noise are analyzed.Spectral estimation is used to simulate the simultaneous Angle measurement of multiple signals.Secondly,the angular measurement of circular array configuration is analyzed,and the Angle situation under different parameters is analyzed.The simulation of multi-signal simultaneous Angle measurement is carried out.Thirdly,this paper puts forward the method of Marine unmanned cluster self-constructed circular array,linear array and orthogonal array compound cooperative positioning,and expounds the basic idea of Marine unmanned cross-domain application.Relevant analysis,charts and data prove the novelty and potential practical value of the paper,and its ideas have positive significance for the development and exploration of related technologies.
