[reported on defenseworld website on January 4, 2022] the Korean Institute of Defense Science (Korean acronym for add) has developed a target detection and classification system based on hyperspectral imaging, which can use the target's unique spectral information for air reconnaissance. This photoelectric technology can significantly improve the target recognition ability of reconnaissance aircraft.


According to different wavelengths, all objects have their unique reflection characteristics. Each object looks different, just like a person's fingerprint. By comparing and analyzing the spectral information of the object or background, the target can be identified according to the principle of wavelength separation by using the light passing through the spectral element (such as prism).


The target recognition technology based on hyperspectral image is an optoelectronic technology, which realizes automatic recognition by analyzing the spectral signal of the target which is difficult to distinguish by the naked eye. Through this technology, not only when the target is camouflaged or part of the target shape is hidden, even if the shape is similar, it is possible to distinguish the real target from the installed enemy simulated target, avoid inducing wrong bombing, and greatly improve the air reconnaissance target recognition ability.


This is the result of a seven-

year project launched by the Korean Institute of Defense Science and Technology (add) in 2014. The project aims to obtain technology based on hyperspectral imaging system, which collects and processes information from the whole electromagnetic spectrum. The goal of hyperspectral imaging is to obtain the spectrum of each pixel in the scene image, in order to find the target, identify the material or detect the process.


From 2014 to 2021, add conducted hyperspectral technology research on aircraft mounting through the core technology business of the defense acquisition program administration (DAPA). In this way, some main components such as imported spectral elements and detectors have been guaranteed by domestic technology.

In addition, in order to apply hyperspectral technology to air reconnaissance system, a prototype meeting the environmental conditions required for aircraft installation was manufactured, the environmental test of durability inspection was carried out, and the function / performance test including aerial photography test was developed. Test evaluation completed successfully.


This research result lays a technical foundation for the application of military hyperspectral image target recognition technology in domestic surveillance and reconnaissance system. This achievement is expected to overcome the technical limitations of the existing reconnaissance system and become the cornerstone of the development of new concept target recognition technology.
