Some spectrum indicators, such as central length, SNR, spectral resolution affect accuracy of water quality retrieval, but are ignored due to the limitations of a single sensor. Take Chlorophyll a retrieval as an example, the sensitivity analysis was conducted using single band, first-order differential and band ratio methods. The results indicated that optimal central wavelength would change because...
Nitrogen is one of the most important nutrients in crop growth and development. To study the problem of spectral index setting of intelligent remote sensor for crop N prime inversion, and effectiveness of quantitative evaluation and other issues in different application requirements, with winter wheat for example to study the impact of quantitative model inversion of center wavelength, SNR and band...
The TASI instrument has 32 spectral band covering 8µm ∼ 11.5µm. The main goal of this paper is to analyze the SNR of each band and the temperature accuracy based on wavebands selection. SNR is calculated by RLSD algorithm. The TES algorithm selects three empirical relationships (MMD, MMR, and VAR). The band of least SNR was removed one by one from residual bands, and the temperature errors were computed...
