摘要
为了提高机载平台在反介入/区域拒止空间中的生存力,研究了射频隐身要求下的综合导航方法。首先,分析了塔康、伏尔以及高度表在无线电静默时,实现综合导航的原理。其次,推导了综合导航的误差计算公式,讨论了不同测向、测高误差以及观测数据不同步对综合导航精度的影响。仿真结果表明,在无线电静默模式下,塔康、伏尔以及高度表能实现综合导航,在测向误差为0.5°时,100 km处的导航精度为3.2%R。
To improve the survivability of the airborne platform in the A2/AD （ anti-access/area-denial） environment, the integrated navigation method is studied according to the radio frequency stealth. The principle of the integrated navigation is proposed based on the TACAN （tactical air navigation sys- tem） , VOR（ VHF omnidirectional range） and altimeter while they are maintaining radio silence. Second- ly, the error formula of the integrated navigation is deduced. The influences of direction finding error, height error and the asynchronous observation are discussed. Simulation results show that the TACAN, VOR and altimeter can be used to realize integrated navigation with the radio silence mode and the navigation accuracy is 3.2% R in 100 km while direction finding error is 0. 5 degree.
