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。
In order to improve the survivability of airborne platform in anti-intrusive / regional rejection space, the integrated navigation method under RF stealth requirements is studied. First of all, it analyzes the principles of Tacon, Volta and Altimeter to realize integrated navigation when the radio is silenced. Secondly, the formula for calculating the error of integrated navigation is deduced. The effect of different direction finding, height error and observational data synchronization on the accuracy of integrated navigation is discussed. The simulation results show that Taconic, Volta and altimeter can achieve integrated navigation in radio silence mode. The navigation accuracy at 100 km is 3.2% R when the DF error is 0.5 °.
