遥感数据的反射率转换基本上可以分为3 种: 第1 类方法利用辐射传输方程建立大气传输模型;第2 类基于图像本身,求出相对反射率;第3 类是参照已知地物的反射率及反射辐射,求出图像DN 值与反射率之间的经验关系。通过对几种遥感数据反射率转换方法的分析,采用经验线性法对机载成像光谱仪PHI数据进行了反射率转换,并对转换结果进行了分析。

The methods for obtaining the reflectance curves of red tide organism water body are systematically studied. It is shown from the comparison between the reflectance curves obtained by two kinds of inversion method and the actual reflectance curves that the inversion results obtained by the empirical linear approach are the most approximate to the actual reflectance curves. Furthermore, the spectral characteristics of normal seawater and red tide organism water body are analysed to extract the characteristic...
