Presently, small satellites with hyperspectral imaging payloads have been used for target detection, environmental monitoring, and forest mapping. All these applications involve the same process of recording the spectra of target/object of interest over densely sampled contiguous spectrum, usually from 400 to 2500 nm. Once a target spectra is recorded, it is matched with reference spectra library for detection. The accuracy of spectra matching highly depends upon the accuracy of radiometric calibration of the hyperspectral imaging payload. This paper presents a study of three methods of absolute radiometric calibration used by various hyperspectral imaging systems in VNIR region, namely Hihara method, Mitsunaga method, and Xiujuan method. Out of the analyzed methods, Hihara method performs the best.
