| 英文摘要 | Ccd and wfi are payloads in the visible light and near infrared bands on cbers satellites and they have not been applied widely, especially wfi. this article mainly probes into the potential of these two sensors' application in the vegetation monitoring and analyses the influences of radiometric calibration, atmosphere conditions and sun-observing geometry, etc. on ndvi obtained from these two sensors respectively. in addition it analyses the effect of the spectral response difference of red and near infrared spectral bands in ccd and wfi sensors on ndvi. results indicate that radiometric calibration is the most important factor on ndvi, which cannot be applied to vegetation monitoring without radiometric calibration. results also demonstrate that near surface ndvi is different greatly from that of toa which change with atmosphere conditions. the study shows that ndvi is also affected by the non-lambertian character of surface and the change of the atmospheric path with the observing geometry. and ndvi of wfi is higher than that of ccd. they are very different because of their spectral difference, but they have a good linear relevant relationship. |
