Description

This paper deals with the possibility of quantitative remote sensing of water quality. Particularly, influence of light reflection on water surface in this remote sensing and its removal method are discussed. As a matter of course, reflected light of sky light or sun light on water surface acts as noise only.<BR>First, reflectance of water surface is compared with spectral reflectance of turbid and clear water in the 0.4-0.7, μm wavelength range. As a result of comparison, reflectance of water surface is as large as another one. Therefore, it shows that elimination of the reflected light from water surface is indispensable to this remote sensing. Then, to eliminate this light, basic form of MSS sensor used polarization characteristics is investigated, and ability of this sensing method for real sea surface is examined.<BR>It is concluded that the influence of the reflection on water surface can be eliminated by conical scanning type sensor equipped with polarized filter, and that effectiveness for real sea surface is confirmed.
