| 摘 要： | 利用Savitzky-Golay滤波信号处理方法,分析了南黄海、北东海2003年春季水色遥感试验所取得的遥感反射率和表层悬浮体取样数据,以期探讨该海区近岸二类水体表观光谱及其导数光谱特性,及遥感反射率及其导数与水体表层总悬浮颗粒物浓度(TSS)和悬浮泥沙浓度(SS)的关系。结果表明,遥感反射率及其一阶导数均适于水体总悬浮颗粒物浓度与悬浮泥沙浓度反演,但其更高阶导数通常会抑制悬浮泥沙的作用则不建议采用;遥感反射率及其一阶导数与ln(TSS)、ln(SS)的相关性较其与TSS和SS更为显著。基于相关分析所筛选出的较优波段,建立了南黄海、北东海水域春季总悬浮颗粒物浓度与悬浮泥沙浓度统计反演模式。

| Abstract: | An experimental above-water radiance measurement campaign was conducted during spring of 2003 in the Yellow Sea and East China Sea, with a co-incident water sample for each measurement. The Savitzky-Golay smoothing was employed to filter field spectral signature and to derive the first and second-derivative spectra. Remote sensing reflectance (Rrs) and its derivatives were analyzed and their correlation relationships with the concentrations of total suspended solid (TSS) and suspended sediment (SS) were dem... |
