Calibration and application of airborne pushbroom hyperspectral imager (PHI)

摘要

Pushbroom Hyperspectral Imaging technology is a new method to acquire the imaging spectrum data. Based on the area CCD technology, pushbroom imager can provide the higher SNR and more bands. Since 1995, Shanghai Institute of Technical Physics was developing the Pushbroom Hyperspectral Imager. In the paper, two generation of pushbroom hyperspectral imager (PHI) and the principle of instrument are introduced. The method and result of spectral calibration and radiation calibration are written in detail. PHI had been used in remote sensing of environment monitoring, geology study, oil and gas prospecting, vegetation, ocean observation, city layout, fine agriculture, forest fireproofing at home and aboard.
