摘要
研究了基于小波分析的飞行数据预处理方法,给出了数据处理模型,并用某型飞机的飞行数据进行了验证。结果表明,与传统的预处理方法相比,小波分析方法不需要过程误差的先验知识,能够同时完成异常值的剔除和数据滤波任务,具有较好的实用性。
A method of pretreatment of flight data based on wavelet is studied and the model of data processing is pro- posed.The method is validated by the flight data from a certain aircraft.The result demonstrates that this method does not require the prior knowledge of process error and also can fulfill the tasks of singular data detection and correspond- ing data filtering simultaneously.
