摘要：

In　order　to　effectively　alleviate　the　effect　of　noise　in　spectral　signal,　stationary　wavelet　is　applied　to　process　the　spectral　signal　in　this　paper.　The　simulation　result　of　stationary　wavelet　transform　and　classic　wavelet　transform　on　wheat　canoy　and　rice　canoy　respectively　show　that　both　wavelet　are　effective　in　alleviating　the　effects　of　noise,　while　stationary　wavelet　gets　a　better　SNR　and　reserves　character　of　signal.　©　2011　IEEE.
