DATA ANALYSIS OF SPECTRAL SIGNATURE OF SEA WATER IN BOHAI BAY -COMPLEX CORRELATION ANALYSIS

Abstract:

Spectral reflectance of sea water depends on both ehlorophyll-a concentration and suspended sediment, so the complex correlation analysis approach was adopted in data analysis of spectral reflectance of sea water to select the independent variables (reflectance) which have the highest complex correlation coefficient with the dependent variables (chlorophyll-a concentration and suspended sediment content) and to determine the complex- regression equations for quantitatively relating sea truth measurements to remotely sensed data. The results obtained show that the complex correlation analysis approach is better than the single correlation analysis approach in increasing l) the correlation coefficients of remotely sensed values calculated from regression equations to sea truth measurements and 2) the confidence.
