摘要
应用傅立叶滤波和导数法等信号处理技术对获得的不同灌溉条件小麦冠层的反射光谱进行处理，选出最能有效区分小麦不同灌溉条件的波长，用这些波长对应的反射率为指标，用模糊聚类（ＦＣＡ）方法对不同灌溉条件的小麦进行区分。
Using Fourier filtering and derivative to process the reflectance spectroscopy of wheat under different irrigational conditions.Select the wavelengths which can distinguish wheat under different irrigational conditions.Wheat under different irrigational conditions is distinguished by fuzzy cluster analysis (FCA) with the reflectance rate of the selected wavelengths.
