Research on Relative Navigation Technology of Aircraft Formation

随着未来编队协同、空中加油等对相对导航功能要求的不断提高,而以往的相对导航信息处理方法对平台间导航参数传输的频率及延时等都有较为苛刻的要求,一定程度上影响了相对导航功能的稳定性。因此,本文研究了一种相对导航信息处理方法,首先介绍了整个系统的工作原理,在此基础上构建了相对导航信息处理架构,并建立了应用性较强的卡尔曼滤波方程,研究了利用伪距差分方式获得相对观测信息的计算方法。仿真结果表明,相对导航信息处理方法表现出良好的性能,编队内僚机均可获得连续平稳、高精度的相对导航信息。

With the continuous improvement of the formation cooperative and aerial refueling needing of the relative navigation function, however, the former information process methods of relative navigation have rigorous demand about the frequency and the time delay of the navigation parameter transmitting between the different platforms, and the above problems affect the stability of relative navigation function in a certain extent. Accordingly, an information process method of relative navigation is studied in this paper. First, the working principle of the whole system is introduced. Secondly, the information process architecture of relative navigation and a very practical Kalman filter equation are established and the obtaining method of relative observed information is studied using the differential pseudo-range means. Finally, the simulation results show that the research method in this paper has the better performance, and all the wing planes can get continuous and smooth relative navigation information with highly precision.
