摘要
本文利用地物光谱仪对太湖水体进行了光谱测量和同步采样分析 ,对获得的数据尝试用光谱分离法进行分析 ,从中分离出蓝藻和悬浮物的特征波峰 ,建立波峰高度与同步水质采样得到的叶绿素 a浓度和悬浮物浓度的对应关系 ,得出其遥感定量反演算法 。
The water from Tai Lake was analyzed by spectrum measurement and synchronous sampling with field portable spectroradiometer. The characteristic wave peaks of cyanobacteria and suspended particle were obtained from the spectra, and the corresponding relations between the heights of wave peaks and the concentrations of chlorophyll a and suspended particle were built. As a result, a quantitative retrieval algorithm is deduced, and the algorithm is applied in the image acquired by OMIS imaging spectroradiometer.
