Radiation Object Map Navigation through Double Stations TDOA Measurement

辐射源目标地图导航相对于传统的无线电导航方式来说,具有极强的隐蔽性和天然的抗外界干扰能力,利用辐射源目标地图这一基础信息条件,提出了双站时差式导航新方法,建立了相应的导航定位模型,阐述了该模型的迭代求解步骤与过程,分析了典型应用条件下模型的变化形态和对应的工程物理意义,仿真结果表明该方法能有效实现双站导航定位,从而为多样化导航的实现和电子侦察设备的多功能应用提供了新的参考。

Radiation object map navigation has more strong concealment and intrinsic antijamming capability than traditional wireless navigation methods. The novel method about double stations TDOA （time difference of arrival） measurement navigation is put forward by utilizing radiation object map information and the iterative resolving approach is discussed for these location equations. The model diversification and engineering physical significance are analyzed for various application conditions. The feasibility and validity of this method are demonstrated by simulation experiments, providing a new reference for diversiform navigation and multi-function application of the electronic reconnaissance.
