基于测速定轨的一类自适应样条滤波方法

Self-adaptive Spline Filter Approach for Trajectory Determination by Velocity Measurement

提出了一种测速定轨的实时算法。该方法基于样条表示飞行轨道速度参数 ,在只有多个测速元信息的情况下 ,建立了自适应Kalman滤波递推算法 。

Based on spline filtering, this paper presents a novel self-adaptive approach for trajectory determination by using velocity measurements. The spline function is adopted to express the parameters of the trajectory so that an iterative algorithm of self-adaptive Kalman filter is established. When information of velocity measurement is merely provided, this approach can give real-time trajectory parameters of the aircraft with high precision .
