说明：  应用MatLab软件进行插值与拟合的程序代码(Application of MatLab software interpolation and fitting code)

1.对染噪doppler信号进行小波包3层分解：分解层次j=1,2时，都是信号的概貌；当j=3时，反映概貌的已几乎不含噪声分量，而其它噪声分量的幅值已很小。 2.对加噪Blocks信号进行不同阈值及不同阈值的使用方式降噪。 (1. On noise pollution doppler signal decomposition of wavelet packet Layer 3: decomposition level j = 1,2, are the signal profiles when j = 3 to reflect the general picture has been almost non-noise component, while other noise components amplitude has been very small. 2. Blocks of noise signals of different thresholds and different thresholds for the use of noise reduction methods.)
