| 摘 要： | 遥感模型PROSPECT可以反演植物叶片生化组分,不同的波段组合将会导致不同的反演结果。提出了一种带约束波段相关性最小原则的波段选择算法,并用模拟数据和实测数据对所选波段的效果进行了验证。结果表明:对于模拟数据,反演准确率超过99%;对于实测数据,叶绿素和水分的反演精度稍有提高,干物质的反演精度提高较明显。

| Abstract: | The remote sensing radiative transfer model PROSPECT may be used to retrieve the biochemical components of vegetation leaf,the inversion accuracy may be influenced by the bands combination.A bands selection method based on the constrained least correlation of wavebands was proposed.Inverted results based on the selected bands were validated and compared with the results of full bands based method for simulation and measured data.The results showed that,for simulation data,the inversion accuracy of the propo... |
