摘 要: 分析了某型飞机的磁带式飞行数据记录器造成数据帧丢失的原因和飞参数据曲线的分形特征,研究了分形插值过程中垂直比例因子对分形维数的影响,利用分形插值的方法对丢失的飞行数据进行估计。与传统的基于线性插值估计的方法相比较,实验结果表明该方法在估计短时间剧烈变化的参数时有更好的效果。 On the basis of analyzing the reason of losing data frame recorded by tape recorder quipped in a certain aircraft and the fractal character of flight parameter curve,the effect of vertical ratable factor on fractal dimension in fractal in- terpolating process is studied.The losing flight data is estimated by the use of fractal interpolating method.The result indicates that in the situation of estimation the flight data varying quickly in short period of time,this method has a bet- ter effect than the traditional linear interpolating method.
