Wavelet Transform (WT) technology of multiresolution feature extraction is studied to identify and quantitatively analyze remote sensing FTIR spectra by Mexican hat function. The signal is performed by continuous wavelet transform (CWT).

• 利用小波的信号多尺度边缘特征提取，采用墨西哥帽函数小波对所获取的遥感傅里叶变换红外光谱信号进行连续小波变换，从而达到识别和定量解析遥感光谱的目的。
