摘要：

为了给局部区域内的高速物体提供高精度的定位,基于网络自校准算法提出新型的区域定位增强技术的方案.该方案利用载波相位和距离变化率之间的关系,通过载波相位变化来描述飞行器轨迹并推导出数学模型及其矩阵表示,结合扩展卡尔曼滤波来求解飞行器的运动轨迹.对于整个方案不需要依赖卫星信号,在隧道等卫星信号遮蔽区域发挥该方案独特的优势.实验设计和仿真结果证实了该方法的可行性和正确性.当飞行速度达到4.2 km/s,距离在60 km之内时,精度可以达到dm级别甚至更低.
Abstract:

A new area positioning model based on self-calibration algorithm was proposed in order to increase the positioning accuracy of high speed aircraft in the special area. The model depicted the trajectory and deduced the mathematical matrix by the relationship of carrier phase and range rate. The aircraft trajectory was obtained with extended Kalman filter. The approach doesn’t rely on the satellite signal, which makes it convenient and prevailing in tunnels. The experiment design and simulation results showed the feasibility and validity of the model. When aircraft’s speed approaches 4.2 km/s and the distance is within approximately 60 kilometers, the accuracy can reach decimeter order of magnitude or even lower.
