Qin, XL; Zhu, X; Yang, F; Zhao, KR; Pang, Y; Li, ZY; Li, XZ; Zhang, JX (2013). Analysis of Sensitive Spectral Bands for Burning Status Detection Using Hyper-Spectral Images of Tiangong-01. SPECTROSCOPY AND SPECTRAL ANALYSIS, 33(7), 1908-1911.

Abstract
To obtain the sensitive spectral bands for detection of information on 4 kinds of burning status, i.e. flaming, smoldering, smoke, and fire scar, with satellite data, analysis was conducted to identify suitable satellite spectral bands for detection of information on these 4 kinds of burning status by using hyper-spectrum images of Tiangong-01 (TG-01) and employing a method combining statistics and spectral analysis. The results show that; in the hyper-spectral images of TG-01, the spectral bands differ obviously for detection of these 4 kinds of burning status; in all hyper-spectral short-wave infrared channels, the reflectance of flaming is higher than that of all other 3 kinds of burning status, and the reflectance of smoke is the lowest; the reflectance of smoke is higher than that of all other 3 kinds of burning status in the channels corresponding to hyper-spectral visible near-infrared and panchromatic sensors. For spectral band selection, more suitable spectral bands for flaming detection are 1 000. 0 similar to 1 956. 0 and 2 020. 0 similar to 2 400. 0 nm; the suitable spectral bands for identifying smoldering are 930. 0 similar to 1 000. 0 and 1 084. 0 similar to 2 400. 0 nm; the suitable spectral bands for smoke detection is in 400. 0 similar to 920. 0 nm; for fire scar detection, it is suitable to select bands with central wavelengths of 900. 0 similar to 930. 0 and 1 300. 0 similar to 2 400. 0 nm, and then to combine them to construct a detection model.
