| 摘 要： | 本论文主要是研究卡尔曼滤波参数混合技术应用于民用飞机相对导航系统。文中重点在于讨论两架飞机相对位置误差的演变。因此首先研究了飞机绝对导航位置误差的演变。讨论了惯导系统(INS)和卫星定位系统(GPS)的卡尔曼滤波混合。此外，讨论相对导航条件下参数混合以及在下列两种不同的情况下的混合结果：1、飞机间相互传送本机混合后的导航数据；2、未经混合的导航数据传送后再混合。采用MATLAB进行仿真，得到不同方式的导航系统相对位置估计误差演变。

| Abstract: | This paper discusses mainly the technique of parameter hybrid of Kalman filter applied in the system of relative navigation.It focuses on the evolution of relative position error of two airplanes.At first,we have studied the evolution of the absolute navigation position error.Then we have discussed the hybrid of Kalman filter of the INS and GPS.We also have discussed the parameter hybrid of relative navigation and obtained the result of hybrid under the two different conditions as following:(1)the navigation data after hybrid is transmitted between airplanes.(2)the hybrid of the navigation data after transmitting each other.Finally we have obtained the evolution of the estimate error of relative position of navigation system under the different modes with the MATLAB simulation. |
