基于Cardinals三次样条曲线的航迹生成算法实现

根据军用飞机飞行参数记录系统提供的飞行数据, 提出了一种利用Cardinals三次样条曲线进行航迹生成的算法。经过对离散点航迹误差修正及样条曲线的讨论, 给出了实时计算任意时间点飞机质心位置的公式, 为开发可在普通PC机上运行的军用战机飞行过程再现软件, 提供了条件。

Algorithm of Generating Flight Paths Using Cardinals Spline

An algorithm of the generation of flight paths using the cardinals spline from flight data provided by the flight parameter measuring system is proposed .An formula of the real-time computation of a centroid position of aircraft at arbitrary time point is given through flight path error correction at discrete points and the discussion of spline and provides a basis for the development of a flight path reproduction software for military aircraft that will run in a personal computer.
