三频带信号分离的样条函数方法

Spline Method of Separating Signal with Three Frequency Bands

本文提出了三频带信号时频处理的样条函数新方法．该方法能够按不同频率特性自动地对信号进行分离和处理．本文从理论上证明了最优空间的等价性定理和逼近空间的相容性定理．应用该方法对运载火箭的外弹道跟踪测量信号进行分析处理，成功地分离了测量信号中的轨道、漂移误差和随机误差．

This paper presents spline time frequency method for processing signal with three frequency bands.The method can separate and process signal by frequency characters automatically.Equal theorem of optimal space and consistent theorem of approximate space are proved.Applying this method to process the measured tracking signal of trajective missile,we successfully separate true trajective,draft error and random error.
