Hyperspectral remote sensing has been widely used in many fields such as ecological environment, geological survey, target detection and so on. The premise of hyperspectral remote sensing application is to obtain high-quality quantitative remote sensing data. Due to the limited number of hyperspectral satellite payloads, airborne hyperspectral remote sensing has played a leading role in hyperspectral applications because it can obtain higher spatial resolution data and higher work efficiency. This article elaborates on the important links of the hyperspectral data acquisition process and data preprocessing process, as well as the working principle and theoretical basis of the sensor. Give scientific research workers an intuitive and scientific understanding of the data production process. Research content ranging from the spectrographic imager components, laboratory calibration, installation, mission planning, engineer 's instrument operation on the plane and data preprocessing.
In this work, the workflow of airborne thermal infrared hyperspectral technology in the actual application process is reviewed. Using the Thermal Airborne Spectrographic Imager (TASI-600), a hyperspectral thermal infrared imager manufactured by ITRES Research Limited as a case study, the work process including instrument calibration, collecting the region information of interest, data processing and analysis is elaborated. The value and effect using thermal infrared data obtained through TASI-600 is demonstrated. This work provides ideas and references for further study and investigation on the application of airborne thermal infrared hyperspectral remote sensing.
