First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   Hyperspectral features about suspended substance in some representative areas, Lake Taihu, China - art. no. 619901 期刊论文  OAI收割 Remote Sensing and Space Technology for Multidisciplinary Research and Applications, 2006, 卷号: 6199, 页码: 19901-19901 作者:  Ma, RH;  Dai, JF 收藏  |  浏览/下载：17/0  |  提交时间：2012/03/08 Lake Taihu  hyperspectra  spectral feature  water quality parameter  suspended substance  total suspended matter  the first derivative  the second derivative  water colour remote sensing   The primary studies on the relationships between soil properties and canopy field spectra of rice in the Liaohe River Delta, P.
