China's first airborne thermal infrared hyperspectral imager was successfully developed



On March 31st, 2016, the Ministry of Science and Technology organized and accepted the acceptance meeting for the “Project Development of a Spaceborne Thermal Infrared Hyperspectral Imager” Prototype in the 863 Program Earth Observation and Navigation Technology in Shanghai.
Compared with visible light and short-wave infrared, hyperspectral remote sensing has unique advantages in thermal infrared. The use of on-board or satellite platforms to obtain fine-spectrum information on the thermal radiation of ground objects can more effectively identify ground objects and resolve targets, and play a major role in geological surveys. Thermal infrared hyperspectral imagers can also be widely used. In areas such as surface temperature detection, urban heat flow analysis, environmental disaster monitoring, and mineral rock identification, the business sector in China is in urgent need of thermal infrared hyperspectral data. This project completed the design of spaceborne infrared hyperspectral imaging payload for the first time in China, and proposed and validated the overall technique of “push scan imaging+extended wavelength thermal infrared detector+dispersive spectroscopy module+background suppression module+on-board real-time calibration”. The route, breakthroughs in key technologies, successfully developed China's first airborne thermal infrared hyperspectral imager with independent intellectual property rights.
The above achievements have successfully completed flight verification. The achievements of the project are of great significance in further promoting the application of hyperspectral infrared imaging remote sensing in the fields of land and resources management, mineral resources investigation, pollution gas control, and surface temperature monitoring.
